It willnot work on earlier versions of this operating system. If you didn't install an operating system yet, we recommend you to use Microsoft Windows 7, asWindows XP is no longer maintained.The software is build as 32 bit software, but will run on both 32 and 64 bit Windows operating systems.When you are going to post-process soundings (3D, contour generation, matrix generation etc.), werecommend a computer with at least a dual-core processor and 2 Gigabyte of free RAM. You will alsoneed sufficient space on the hard disk to store maps, soundings and matrix files.InstallationTo start the installation, and you own a hardlock or dongle, run the setup_hydro_full.exe downloadedfrom the website, or from the program CD.When you want to try the software, and you do not have a dongle yet, you should run thesetup_hydro.exe which is a demo version with some exporting and printing functions disabled.When using Windows Vista or newer operating systems, it is recommended to run the setup program asAdministrator, as shown in the image below:Eye4Software Hydromagic 6.04© 2014 Eye4Software B.V.Just follow the steps of the setup program. After setup has completed, the software will startautomatically.2.2 ActivationActivationDongleEye4Software Hydromagic is protected against unauthorized use by an (USB) dongle or other softwareprotection device.To run this software, the dongle has to be plugged to an USB port, and should not be removed until thesoftware has been shut down.Activation CodeIn some rare cases it is possible that you have received a version of the software which is activated by aConfiguration 5© 2014 Eye4Software B.V.code which is generated using an unique code generated from your computer's configuration. You can use this unique code to obtain an activation code by sending us an email to sales@eye4software.com.To obtain the unique system code, select the "About Hydromagic" option from the "Help" menu.If you have a version that supports activation using an activation code, the following screen should bedisplayed:When the "Enter License Code..." button has been disable, you own a regular demo version of thesoftware, or a version that is protected by a dongle.If you are unable to use a dongle, please contact support on how to obtain the correct version. To request an activation code, press the "Activation Code..." button and follow the instructions on thescreen that appears:Eye4Software Hydromagic 6.06© 2014 Eye4Software B.V.When you have received the activation code from us, enter it in the "Activation Code" box, and click"OK".The about dialog should now look like this:2.3 Hardware Configuration2.3.1 Configuring an NMEA0183 compatible GPSIntroductionNMEA0183 GPS and RTK ReceiversConfiguration 7© 2014 Eye4Software B.V.The most important device required for this software to work, is the GPS receiver. At this moment, allGPS devices with a NMEA0183 compatible connection are supported. The GPS is used to get position, course, speed and information on GPS quality and / or precision.When using a RTK receiver, you should be able to get real time tide information as well.In order to connect a GPS receiver, you need to have at least one available serial port. If there is no portavailable, you can add a serial port by using an USB-to-Serial converter or a NMEA0183 data combiner equippedwith an USB port. When using such a converter, make sure it is connected at the time you are going to configure the GPS.When you have no control on which sentences are sent by the device, it is recommended to only selectthe GGA and VTG options in the NMEA0183 settings. NMEA0183 Echosounders or FishfindersMost echosounders these days do support their own proprietary output format as well as the morestandardized NMEA0183 protocol. If your echosounder does not support the NMEA0183 protocol, you should be able to configure it usingone of the plug-ins shipped with Hydromagic.In order to connect an echosounder, you need to have at least one available serial port. If there is no portavailable, you can add a serial port by using an USB-to-Serial converter or a NMEA0183 data combiner equippedwith an USB port. When using such a converter, make sure it is connected at the time you are going to configure thesounder. In addition to the serial communications setup, you also have to check the echosounder offsetconfiguration.Supported NMEA0183 sentences for GPS devicesHydromagic is able to decode the following NMEA0183 sentences used by GPS and RTK devices:Sentence Description$GPGGA Global Positioning System Fix Data, Time and Position$GPGLL Geographic Position - Latitude and Longitude$GPGSA GPS DOP and Active Satellites$GPGSV Satellites in view$GPRMC Recommended Minimum Navigation Information$GPVTG Track Made Good and Ground Speed$GPZDA GPS Time$PTNL,GGK Trimble RTK positioning data and ellipsoidal heightEye4Software Hydromagic 6.08© 2014 Eye4Software B.V.Supported NMEA0183 sentences for soundersHydromagic is able to decode the following NMEA0183 sentences used by echosounder devices:Sentence Description$SDDBK Depth below keel$SDDBS Depth below surface$SDDBT Depth below transducer$SDDPT Depth and keel offsetConfigurationTo add the GPS device to the configuration, select "Preferences..." from the options menu and select the"NMEA0183" tab. The following window should now appear:Configuration 9© 2014 Eye4Software B.V.Select an unused NMEA0183 channel and click the "Setup..." button for that channel. The followingdialog should appear:Device SettingsSerial PortUse this drop down box to select the COMxx number of the serial port the device is connected to.This can be either a regular serial port, or a virtual serial port, which are used with USB to serial andBluetooth adapters.If you didn't connect your serial converter or Bluetooth dongle, you can connect it when this dialog isopen, and click the "Refresh" button to re-detected the available serial ports.Serial BaudrateThe default serial baudrate for NMEA0183 devices is 4800bps. However, some hardware use otherspeeds (for instance, an AIS receiver will use 38400).When configuring a RTK receiver, the serial speed can sometimes deviate from the standard. 9600,19200 and 38400 bps are mostly used on these devices.Serial FormatYou can leave this setting at it's default value. Devices that use NMEA0183 protocol with other settingsare very rare.LatencyEye4Software Hydromagic 6.010© 2014 Eye4Software B.V.Latency (sometimes called lag) is the time between a measurement has been made (for instance aposition fix, or depth) and when the serial data is received by the application.If this value is know for a certain device, you can enter it here to get more accurate soundings.NMEA0183 SettingsCRC CheckSome devices support a NMEA0183 CRC checksum. If you want to make use of this, enable this option.When a sentence does not contain a CRC, the CRC check will be skipped, so it is safe to leave thisfeature on.Talker IDUse this option to filter NMEA0183 sentences by talker ID. It sometimes happens that both echosounderand GPS devices are transmitting GPS sentences, in this case you can either select the GPS orechosounder by specifying "GP" or "SD" in this field.SentencesTo select which NMEA0183 sentences will be decoded, and which ones will be ignored on this channel,click the "Select sentences..." button.The dialog that appears allows you to select which sentences are used. For most GPS devices,selecting only the GGA sentence will suffice. If you choose to use the heading and speed calculated by the GPS device, you should also select theVTG sentence.For a echosounder, you should use either the DBS, DBT, DBK or DPT sentence.Configuration 11© 2014 Eye4Software B.V.Testing the device(s)When everything has been configured correctly, and the device has been turned on, you should havesome green values in the dataview window.Serial Communications MonitorEye4Software Hydromagic 6.012© 2014 Eye4Software B.V.You can always check whether data is coming in by running the serial communications monitor. To start this monitor, select the "Preferences..." option from the "Tools", and selecting the "NMEA0183"tab. At the bottom of this tab, you will find the "Serial Communications Monitor" section.Click the "Start..." button to start the monitor, and select one of the NMEA0183 channels to monitor theinput.2.3.2 Configuring hardware using pluginsUsing PluginsBy default, Hydromagic can be used with most NMEA0183 devices. To add support for devices not usingthe NMEA0183 protocol, plugins are used. Plugins are small programs that are loaded into the memorywhen Hydromagic starts. The main advantage of using plugins, is that the main program hasn't to bereplaced each time a new device is used. Instead, a new plugin is installed and loaded by the mainprogram. Plugins are installed into the "Plugins" folder in the installation directory selected during setup. Configuring PluginsTo configure and select the plugins to use, you can open the plugins configuration window by selectingthe "Preferences..." option from the "Tools", and selecting the "Plugins" tab. The following window shouldappear: Configuration 13© 2014 Eye4Software B.V.The "Plugin-Manager" automatically detects all available plugins and displays them in the list, along withtheir current status (start or stopped). To start using a plugin, select it and click "Configure..." toconfigure it. This configuration wizard is different for each plugin.After configuring the plugin, you can enable it using the "Start" button. To disable it, use the "Stop"button. The current state of the plugin is stored when exiting the program. When a plugin has beenenabled, it will be started automatically when Hydromagic is started. TroubleshootingWhen a plugin fails to load for some reason, an error icon is displayed as shown in the screenshotbelow: Eye4Software Hydromagic 6.014© 2014 Eye4Software B.V.To find the cause of the error, you can have a look at the eventlog. The eventlog can be displayed byselecting the "Show Event Log..." option from the "Help" menu. In most cases, either the plugin cannotbe start because it is missing, or when you selected a device that is already in use or not longerpresent. Monitoring Serial CommunicationsWhen a plugin has been started successfully, but isn't giving the correct results, you can have a look atits incoming data using the "Serial Communications Monitor".To start this monitor, select the "Preferences..." option from the "Tools", and selecting the "NMEA0183"tab. At the bottom of this tab, you will find the "Serial Communications Monitor" section.Click the "Start..." button to start the monitor, and select the plugin from the drop-down list as shownbelow:Configuration 15© 2014 Eye4Software B.V.2.4 Geodesy Configuration2.4.1 Manage EllipsoidsIntroductionTo open the "Manage Ellipsoids" window, select "Options" => "Coordinate Systems" => "ManageEllipsoids..." from the menu.

Dynamic draft (depending on the speed of the vessel) canbe corrected when processing your raw data files.The transducer of the echosounder measures the water level from the bottom of the transducer to thebottom of the river.The height of the water which is above the bottom of the transducer has to be added to the echosounderoutput, and can be entered here.Most echosounders have the option to enter the distance between the water surface and the transducer, so in this case you do have to disable this option, or you can use it for other corrections.Entering the echosounder offsetTo enter an offset for the echosounder, select "Preferences..." from the "Option" menu. In the dialog that appears, select the "Calibration" tab. You should see the following dialog:Configuration 27© 2014 Eye4Software B.V.The value entered is added to the depth (both high and low frequency depths) reported by theechosounder. To subtract from the sounders value (in case of depth below keel), just prefix the value withthe minus sign "-".To disable the correction, just remove the tick from the "Apply Echosounder Offset" checkbox, or clickthe "Reset" button to load the defaults.Raw data filesPlease make sure the echosounder offset is measured and entered into the software beforerecording any data.The depth written in the raw data files is the depth corrected with the echosounder offset Using RTKWhen you are measuring the elevation of the river bed using a RTK receiver, and the offset between thetransducer and GPS antenna is fixed, you can just enter this offset in the RTK settings tab.Eye4Software Hydromagic 6.028© 2014 Eye4Software B.V.However, we recommend to fill out both the antenna and transducer offset separately in case you everneed the absolute water depths. NMEA0183 compatible echosounders or fishfindersWhen using a NMEA0183 compatible echosounder of fishfinder, whether to enter an offset depends onthe NMEA0183 sentence(s) used to retrieve the depth data.Sentence Depth Value Correction$SDDBK Depth below keel Enter the distance between the keel of the ship and the watersurface.$SDDBS Depth below surface No correction is needed, as the depth is measured from thewater surface.$SDDBT Depth belowtransducerEnter the distance between the transducer and the watersurface.$SDDPT Depth The offset configured in the echosounder is used.2.5.2 Vessel shape and offsetsIntroductionUsing the built in "Vessel Editor" you can specify how the vessel should be drawn on the map.

For more information on S-63, pleaserefer to the next chapter.Loading S-57 mapsS-57 maps can be load into Hydromagic by right clicking "Maps" in the Project View, and selecting the"Import Map..." option as shown in the image below.The file extension for both S-57 and S-63 maps is ".000". The software will auto-detect whether theselected map is encrypted or not.4.3 Loading IHO S-63 ENC'sIntroductionIHO S-63 is a standard for encrypting, securing and compressing electronical nautical charts, alsoknown as ENC's. The standard is using CRC32, SHA1, DSA and Blowfish algorithms to ensureprotected delivery of nautical charts. Most commercial ENC's on the market today are protected usingthe S-63 standard.Each software installation contains an unique hardware id which is encrypted and cannot be read by theuser. Charts purchased for this software will work on this installation of the software only. The hardwareid is encrypted using the OEM and manufacturer id forming the 'Userpermit' which is used to purchaseENC's. Purchasing ENC'sS-63 ENC's can be purchased through your local marine supplies dealer, or online reseller. In order topurchase ENC's you need the 'Userpermit', and register it with the online chart store or your localMap display / Background maps 63© 2014 Eye4Software B.V.reseller. Because the hardware id is encrypted in the Hydromagic registration code or hardlock, it is onlypossible to use S-63 ENC's in registered versions of the software. It is not possible to load these chartswhen using a trial version. Obtaing the userpermitTo obtain the userpermit for your software installation, select the "S63 ENC Permits..." option from the"File" menu, as shown in the screenshot below: This will launch the "S63 ENC Permits" dialog, which contains the userpermit, and can be used toactivate purchased ENC's. When you are using a registered version of the software, the dialog shouldcontain the userpermit which can be used to purchase ENC's. Eye4Software Hydromagic 6.064© 2014 Eye4Software B.V.Activation of purchased ENC'sWhen purchasing ENC's you will receive a "PERMIT.TXT" file from your reseller containing the 'Permits'for the purchased ENC's. After importing this file, you will be able to load these. To do so, relaunch thepermits dialog by selecting "S63 ENC Permits..." from the "File" menu.You can now load the "PERMIT.TXT" file, by clicking the "Load Permits..." button, and selecting thereceived permit file. You only have to do this once, imported permits will be stored until the software isreinstalled.When the file has been imported sucessfuly, you will see something like this: Map display / Background maps 65© 2014 Eye4Software B.V.In most cases the reseller can supply you with a "ENC Base CD" containing all the charts for yourregion. If not, you can download the charts, depending on your reseller, from Primar or IC-ENC.When the ENC's and permits are correctly installed, just select "Import Map..." from the "File" menu,and select the ENC you want to load. When trying to load an enc that has not been purchased, you willreceive error SSE 11 as shown in the table below.When an error occurs during the import of permits, or when loading an ENC, you will receive one of theerrors described in section 4.4.5.

They only contain some image data, and in some cases(GeoTIFF) some georeferencing information. These maps do not support high zoom levels, because theyare limited by the number of pixels the map is stored in.You can load a raster map into your project by selecting "File" => "Import" => "Import Map..." from themenu. GeoTIFF FilesGeoTIFF files are based on the TIFF (Tagged Image File Format) standard. This formatallows you to insert all sorts of tags into an image file. GeoTIFF uses this to storeinformation on calibration info and / or projection information in the file. When you tryto load a map that only contains the calibration info (X,Y boundaries and scaleinformation), you will be asked to set the projection parameters for the map. JPG, GIF, TIF, BMP and PNG Image FilesIt is possible to use your own images to project routes, waypoints, tracks andrealtime position on. These images can be downloaded from the web (for instance,image created with Google Earth or maps exported from OpenStreetMaps.org, orcreated by scanning paper maps. To use these images, they have to be calibrated inorder to be used. This can be done by selecting some well known coordinates on themap, or by entering the boundaries of the map. For more information about calibratingthese maps, see the Calibrating Maps Tutorial. When a file has an associated "WorldFile" the map is calibrated using this information. BSB Nautical ChartsBSB map files are rastercharts designed especially for nautical charts. They are usedby several authorities like NOAA. Nautical maps can often be downloaded for free inthe BSB format. When loading BSB files in GPS Mapping Studio, the map isdisplayed directly, because all geo info is included in the map. BSB maps useLambert Conformal Conic, Mercator and Polyconic projection. Eye4Software Hydromagic 6.068© 2014 Eye4Software B.V.4.5 Supported Vector FormatsSupported Vector MapsVectormaps are files that contain objects instead of image data. A typical example of an object can be aline, point, polyline, polygon and more. Sometimes these objects are also associated with someuserdata or a row in a datatable. Because the vector objects drawn at runtime, there is no limitation onthe zoomlevel like rastermaps.You can load a rastermap into your project by selecting "File" => "Import" => "Import Map..." from themenu. ESRI shape filesESRI shapefiles are vector maps often used to exchange data between GIS and CADapplications. Like DXF files, it contains objects rather then image information. AnESRI shapefiles consists out of 3 parts, a .shp, .dbf and .idx file. The databse andindex files are ignored by GPS Mapping Studio, it only uses the .shp file whichcontains the map objects. The .dbf database file is only used by GIS applications.Map calibration info is extracted from the shp file. When loading an ESRI shapefile,you have to set the projection parameters by hand. AutoCad DXF filesDXF stands for Drawing eXchange Format, and was developed by AutoDesk and isused in AutoCad software products. It is a vector format, this means the file containsobjects rather then just image information ( pixels ). AutoCad DXF files are notdesigned to store georeferencing information, so after loading a DXF map, you will beasked to set the projection parameters. Microstation DGN filesDGN is a vector format used in Microstation CAD software. The software currentlyonly supports the ISFF (Integraph Standard File Formats) DGN format. The newer V8DGN format is not supported yet. In ISFF format, all objects are stored as blocks intoa single file. Each Microstation design file starts with a TCB element, containingglobal information on the file, like scale, units and extends. OpenStreetMap XML filesMap display / Background maps 69© 2014 Eye4Software B.V.OpenStreetMap is a free, web-based, editable map of the whole world. On thiswebsite, you can find both vector and raster mapdata for almost every place on theworld. The data can be exported to a XML format containing all map objects likeareas, natural, buildings and roads. This data can be loaded into the GPS mappingsoftware. The mapping software will render the data automatically using the correctcolors, or you can set your own rendering rules. All OpenStreetMap data is usingWGS84 (World Geodetic System 1984) as reference, so there is no need to setprojection parameters when a map has been loaded. MapInfo MIF/MID filesMapInfo MIF/MID is a propietary format used by MapInfo and other GIS softwarevendors. The format uses a MIF file to store all the features, and a MID file to storethe attribute data. Both files are encoded in plain ASCII. The projection used can bestored in the header of the file. When this information is missing when loading aMapInfo map, you will be asked to enter these parameters after loading the map. ARC/INFO Export filesArc/Info Export is a proprietary format, developed by ESRI, used to export GIS databetween GIS applications. The data is encoded as plain ASCII. Values are encodedin scientific notation with single or double precision. Objects supported are, points,lines, polylines and labels (text). Projection information can be stored in the file, butmost of the times a .PRJ projection file is used. 4.6 Downloading MapsIntroductionIn circumstances where an electronic nautical map or CAD drawing of your surveying area is notavailable, you can use the map download functionality offered by Hydromagic.It allows you to use street maps or satellite imagery from Google, Bing or OpenStreetMaps asbackground image for your project.Tiles are downloaded from the provider of choice, merged into a map image and geo-referenced to theprojection you are using in your project.Therefore you have to select the map projection you are going to use before downloading any maps.Please note that storing map tiles locally breaks the terms of service for a coupleof popular data providers like Google, Bing, and ArcGIS Online.Use this function at your own risk Download Map ToolEye4Software Hydromagic 6.070© 2014 Eye4Software B.V.It is only possible to download maps once you loaded or created a project. To create a new project,select "New Project..." from the "File" menu.To start the map downloading tool, right click the "Maps" folder in the "Project View" and select the"Download Map..." option from the popup menu as shown in the image below.In case you didn't select a map projection for the project yet, you will be asked to do so, if not thedownload tool is displayed.The tool allows you to download street maps or satellite imagery from the following 5 providers:OpenStreetMaps;ArcGIS Map Service;Nokia OVI Maps;Google;Bing (Virtual Earth).Setting area and optionsIn order to download maps, you have to select the area you need a map for, and which provider you wantto use.Use the "Information Source" selection box to select the provider and the type of map (streets orsatellite).The next step is to select the area. Select the smallest area as possible, because the smaller the area,the higher the zoom level and level of detail.You have to enter the upper-left and lower-right WGS84 coordinates of the area you are surveying in. Because the maps are downloaded as 256 x 256 pixel tiles, it is likely that the actually downloaded areais a bit larger then the requested area.You can obtain the coordinates by using a map viewer like Google Earth or others.Finally, select the name of the output file (the file where the map is stored) and whether to add the mapto the project directly.Map display / Background maps 71© 2014 Eye4Software B.V.Depending on the type of map you are using, the image is stored as PNG (streetmap) or JPG(satellite)file..Area selection toolsAs an alternative to enter the coordinates manually, you can calculate boundaries from a waypoint,sounding, boundary, current location or an address.To do so click the "Calculate..." button. The following dialog will appear:Eye4Software Hydromagic 6.072© 2014 Eye4Software B.V.The first three options (GPS Position, Address and Waypoint) can be used to specify the center of themap. To calculate the map extends, you have to enter the map dimensions.When using the last two options (sounding or boundary), the map dimensions entries are disabled, andthe boundaries are copied directly from the area covered by the selected sounding or boundary.Please not that when using the "Find Address..." tool, make sure you are connected to the internet inorder to perform a Geo-Coding lookup.DownloadTo start downloading, just click the "OK" button. Please note that you have to be connected to theinternet at this moment. The download progress is shown in the status bar. First, the tiles are downloaded and merged into alarger images, which is geo-referenced using the projection set.When downloading has been completed, and the "Add generated map" options has been checked, themap will be added to the project and displayed.Map display / Background maps 73© 2014 Eye4Software B.V.4.7 Changing drawing orderChanging map drawing orderIn cases where a map (partially) covers another map, you can control the sequence in which the mapsare drawn.When using multiple maps, always draw vector maps on top of raster maps (unless the raster maps havetransparency).You can also use this option to place vector maps on top of a matrix created by HydromagicMap Order ToolTo change the map order, select "Layers..." from the view menu. The "Map Display Order" dialogappears:Eye4Software Hydromagic 6.074© 2014 Eye4Software B.V.Click the "Move To Front" or "Move To Back" buttons to change the drawing order.Changes will be applied directly. To accept the order, click "OK" to close the tool.4.8 Adding waypoints to the mapIntroductionA waypoint can be defined as a marked position on a map, somewhere on the earth, with knowncoordinates. A waypoint can be part of a route. In GPS receivers, a waypoint is a point that can beselected as a coordinate to navigate to, or it can be used to just display a symbol on a map. Creating a waypointIn Hydromagic, there are multiple ways to create waypoint. You can create one manually from thewaypoint list, click on the map or create by applying a projection from a known waypoint or GPSposition. The easiest way is by clicking on the map. We will demonstrate in a few steps how to do this.Zoom and pan over the map until you find the position you want to place a waypoint. Click the rightmouse button, when pointing the mouse to the position, and select the "Add Waypoint" option. The "AddWaypoint" window will appear. Map display / Background maps 75© 2014 Eye4Software B.V.You will notice that the position of the waypoint is already filled. In this window, you can set someadditional information about the waypoint, like the comment, the name, the symbol to be used on themap etc. The proximity waypoint option will be discussed in a later tutorial, it is mainly used to alert youif you are within a specific distance from the waypoint. Waypoint Properties WindowNameUse this field to set the waypoint name. When creating waypoints, the software will auto generate thewaypoint name in the range "WPT001" ... "WPT999". You can choose your own name, but please note,that in case you want to upload the waypoint to your GPS receiver, you have to keep the maximumwaypoint name length of your GPS receiver in mind. The name must be unique: you can not create morethen one waypoint with the same name.Latitude and Longitude positionThese positions are prefilled when you create the waypoint from the map. If you are creating the waypointfrom the waypoint list, the current position is used. You can change these fields to display the Northingand Easting position using the currently selecting map grid, by checking the "Show position in Northing /Easting coordinates" check box.SymbolEye4Software Hydromagic 6.076© 2014 Eye4Software B.V.The software contains over 160 different symbols that can be used to display your waypoint on the map.When uploading the waypoint to your GPS, the same symbol is used, so you must be sure that thesymbol you choose is also present in the GPS device. The default waypoint symbol is the "BlackRectangle" that is supported by any GPS receiver.DescriptionYou can add a description for the waypoint here. When uploading the waypoint to the GPS receiver,depending on the model you are using, the description will be displayed truncated on your GPS receiver.Waypoint LabelUsing the "BgColor", "FgColor" and "Transparent" options, you can modify the colors of the waypointlabel on the map. When transparent is selected, the background color is ignored, and only the text isdisplayed on the map.Proximity WaypointIf you want to act this waypoint as a proximity point, enable this function. Please note that not allreceivers support this option. When enabled, your GPS will alarm you if you are withing a certain rangefrom the waypoint. Saving the WaypointAfter modifying the waypoint properties, click "OK". When using the settings from the screenshot above,the waypoint will look like this: Modifying or moving the WaypointTo modify the Waypoint after you placed it on the map, you can use either the waypoint list, or right clickon the waypoint, and select "Waypoint Properties", as displayed below: To move the waypoint, click on it and just drag it around on the map. When you release the mousebutton, it's new position is saved. Map display / Background maps 77© 2014 Eye4Software B.V.The Waypoint ListTo view a list off all Waypoints, you can open the Waypoint list, by selecting "View" => "Waypoints"from the menu. From this list, you can remove, add, modify, export and zoom to Waypoints. Eye4Software Hydromagic 6.078© 2014 Eye4Software B.V.4.9 Projecting WaypointsProjecting a waypointWhen projecting a Waypoint, you basically create a Waypoint on a certain distance and heading from aknown position. In Hydromagic, there are multiple ways to project a waypoint. You can project thewaypoint from another Waypoint, a position on the map, a manually entered position or the current GPSposition. In this tutorial, we will project a Waypoint, using another Waypoint as a reference.To open the "Project Waypoint" window, select the "Tools" => "Project Waypoint" option from the menu.The following window will appear: Map display / Background maps 79© 2014 Eye4Software B.V. In this window, you will find 2 buttons, a "Select..." button, to select the source Waypoint, and a "GPS"button which can be used to automatically enter the current GPS position as source location. For thisexample, we will use another waypoint, so we click the "Select..." button and choose a Waypoint fromthe list. If there is no Waypoint in the list, you can walk through the Creating Waypoints tutorial to createa one. Once you selected a Waypoint, the coordinates of this Waypoint are copied into the Latitude /Longitude fields.For this example, we will create a new Waypoint at 100 meters and a 45 degrees course from theselected Waypoint. After we entered these values, we click "Project...". Saving the waypointA "Waypoint Properties" window will appear with the location of the projected Waypoint already entered.You can now modify the waypoint's attributes such as name and symbol. Please note, that when a newWaypoint is created, by default the symbol and label properties are copied from the last createdwaypoint. This might be very handy when creating multiple waypoints that should use the sameattributes. When done, click "OK" to save the waypoint. Eye4Software Hydromagic 6.080© 2014 Eye4Software B.V.Ready When looking at the map, you will find the "WPT002" waypoint projected at an angle of 45 degrees and adistance of 100 meter from the selected waypoint. Map display / Background maps 81© 2014 Eye4Software B.V.4.10 Adding comments to the mapIntroductionIn Hydromagic, it is possible to add comments or labels to your maps. You can use comments or labelsto, for instance, mark places, or to add extra comments about the map before printing it. You can placecomments using any color or Windows font, with or without background.Adding a commentT are multiple ways to add a comment. You can create one manually from the comment list, or click onthe map to place a comment at the current mouse position. The easiest way is by clicking on the map.We will demonstrate in a few steps how to do this.Zoom and pan over the map until you find the position you want to place a comment. Click the rightmouse button, when pointing the mouse to the position, and select the "Add Comment..." option. The"Add Comment" window will appear. You will notice that the position of the comment is already filled out. In this window, you can add acomment to store with the map. You can also change the fore- and background colors and the font usedto draw the comment on the map.Eye4Software Hydromagic 6.082© 2014 Eye4Software B.V.Comment Properties WindowLatitude and Longitude positionThese positions are prefilled when you create the comment by right clicking on the map. If you arecreating the comment from the comment list, the current position is used. You can change these fieldsto display the Northing and Easting position using the currently selected local grid (if set), by checkingthe "Show position in Northing / Easting coordinates" check box.CommentEnter the comment here. It will be appear on the map exactly as you entered it in the "Add Comment"dialog.FgColorThe color used to draw the text and border. If the transparent option has been selected, no border isdrawn.BgColorThe color used to draw the text backgound. When the transparent option has been selected, this valuesis ignored.FontUse this drop down box to select the font for the comment. All installed Windows fonts are displayed.Please note that when the project is transfered to another PC, which does not have this font installed,another font is used.SizeUse this drop down box to select a font size. You can see the result in the preview pane at the bottom ofthe dialog.Saving the commentAfter modifying the comment properties, click "OK" to add the comment to the project. When using thesettings from the screenshot above, the comment will be displayed on the map like this: Map display / Background maps 83© 2014 Eye4Software B.V..Modifying or moving the commentTo modify the comment after you placed it on the map, you can use either the comment list, or rightclick on the comment, and select "Edit Comment...", as displayed below: Eye4Software Hydromagic 6.084© 2014 Eye4Software B.V.To move the comment, click on it and just drag it around on the map.

Map display / Background maps 85© 2014 Eye4Software B.V.4.11 Adding photos to the mapIntroductionIn the Hydromagic, it is possible to add references to image files, like photo's on your maps. The image'swill be showed on the map as a camera icons. When clicked, the photo will appear. Possible applicationexamples include: Store images of buildings in your GIS datasets; Store underwater photo's or sidescan sonar images in your nautical maps; Store images of terrain features in your topographic maps;Adding a photoIn Hydromagic, there are multiple ways to add a photo. You can create one manually from the photo list,or click on the map to store a photo on the current mouse position. The easiest way is by clicking on themap. We will demonstrate in a few steps how to do this.Zoom and pan over the map until you find the position you want to place a photo. Click the right mousebutton, when pointing the mouse to the position, and select the "Add Photo..." option. The "Add Photo"window will appear. Eye4Software Hydromagic 6.086© 2014 Eye4Software B.V.You will notice that the position of the photo is already filled. In this window, you can add a name andcomment to store with the photo. Also, you have to select an image file by clicking the "Browse..."button. At this moment, JPEG, GIF, BMP, TIF and PNG files are supported. Please note that only the path to the image is stored in the project file. In case of a backup, you have tobackup the image files manually. Once the images are moved or deleted, the images can no longer beviewed from the map.Photo Properties WindowNameUse this field to set an unique name for your photo. This name is also displayed on the map below theMap display / Background maps 87© 2014 Eye4Software B.V.camera icon and in the project view. It is not possible to create more then one photo with the samename.Latitude and Longitude positionThese positions are prefilled when you create the photo by right clicking on the map. If you are creatingthe photo from the photo list, the current position is used. You can change these fields to display theNorthing and Easting position using the currently selected local grid (if set), by checking the "Showposition in Northing / Easting coordinates" check box. To find the position using geo-referencing, clickthe "Find Address..." button. You need to have an active internet connection to use this feature.DescriptionYou can add a description for the photo here. This field is optional and can be kept empty.FileDisplays the full path to the image file.

Map display / Background maps 89© 2014 Eye4Software B.V.4.12 Creating BoundariesBoundariesA boundary is required when using volume calculations. It is also used to specify for which area we wantto create a matrix or contours, or to specify a clipping region for certain graphical operations. The easiest way to create a boundary is by drawing a polygon on the map, but it is also possible to enterthe coordinates by hand.Create by using the mouseTo start a new boundary, just click "Boundary Drawing Tool" button in the toolbar: ( ).Secondly, use the mouse to select the corners of the area by left-clicking the on corner locations in themap. When finished, click the right mouse button to store the boundary. The new created boundaryshould now appear in the "Project Explorer". By default a new boundary is named "BOUNDARYXXXX"where "XXXX" is the number of the boundary. Boundaries are drawn as red, dotted lines. The boundarypoints are drawn as red rectangles. Eye4Software Hydromagic 6.090© 2014 Eye4Software B.V.Modify by using the mouseTo modify a created boundary, regardless whether it has been created by entering coordinates or byusing the mouse, can be modified by dragging it's corner point around. First, you have to activate theboundary you want to alter. This can be done by right-clicking on the boundary name in the "ProjectExplorer", and selecting the "Set Active" option. It is only possible to drag the points around when the"Disable Drag and Drop" options is turned off (enabled by default). This can be done from the "Cursor"menu. Create by entering coordinatesWhen your client has supplied a list of coordinates for the area you have to survey, you can also create aboundary by manually entering these points. To do so, right-click the "Boundaries" folder in the "ProjectExplorer" and select the "Add Boundary..." option. The following dialog will appear: Map display / Background maps 91© 2014 Eye4Software B.V.The table shows the coordinates of the corners of the boundary. The toolbar at the bottom of the dialogallows you to insert, delete or alter the coordinates.This dialog can also be used to modify boundaries created by using the mouse, or to rename apreviously created boundary: Button FunctionEdit the selected coordinate.Add a new coordinate to the list.Insert a new coordinate before the selected coordinate.Deletes the selected coordinate(s).Clears the list (delete all coordinates).Reload the list.Show selected coordinate on the map.Toggle coordinates between WGS84 and local grid.Removing a boundaryA boundary can be removed by right-clicking on the boundary name in the "Project Explorer" and byselecting the "Remove Boundary..." option. After a confirmation, the boundary will be removed from theEye4Software Hydromagic 6.092© 2014 Eye4Software B.V.project. 4.13 Cross SectionsCross SectionsIn Hydromagic, cross sections are used to create a theoretical 3D design of the area you want to use toperform volume calculations. The sections are in fact lines from shore to shore containing depth orelevation information relative to the distance from the shores or riverbanks.By using a boundary, it is possible to auto generate cross sections from bank to bank (automaticplacement). It is also possible to place them by dragging the sections at the correct place by using themouse (manual placement). Automatic placementUsing automatic placement, cross sections will be generated to fill a specified boundary. The directionof, and the distance between the sections can be selected. To use automatic placement, select the"Generate Sections" option, by right clicking the "Sections" folder in the "Project Explorer". The followingdialog will appear: For the "Line Direction" you will normally specify the heading perpendicular to the shore or riverbank. Youcan measure the direction of the shore using the built in "Distance and Bearing" tool.The "Line Distance" depends on the size of the area, in this example we leave it to the default value, 10.0meters.Use the section name prefix when you have multiple sets of sections. The software will start the namesof the generated sections with this prefix, so it is more easy to determine to which set a section belongs.In this example, we will use "DK" as prefix for the section names.Finally, select the area you want to use as clipping area for the sections. To start generating crosssections, fill in the required fields and click "OK". The cross sections are now calculated and displayedon the map: Map display / Background maps 93© 2014 Eye4Software B.V.Manual placementIn some cases, the automatic placement will not suffice, for instance for irregular areas or at places theriver makes a turn. You can then make use of manual placement (eventually in combination withautomatic placement).To create a new section, right click the position of the new cross section, and the following dialog willappear: Eye4Software Hydromagic 6.094© 2014 Eye4Software B.V.Enter a name for the newly created section and click "OK" (we will discuss the other options of thisdialog in the next chapter). A new section will be created with a default length and azimuth. You can usethe mouse to rotate, resize and move the section in the right place.Moving, resizing and rotating cross sectionsAfter automatic or manual placement, you will notice that a single cross section is drawn as a dashedpurple line with 3 anchor points. You can select these points with the mouse to move or rotate the crosssection using the map.By dragging the center point of the cross section, you can drag and drop it to the new position. In orderto rotate or resize it, use either one of the start and end points of the cross section.Please note, that in order to drag and drop any objects on the map, you have to disable the "Disabledrag and drop" option from the "Cursor" menu. Map display / Background maps 95© 2014 Eye4Software B.V.Delete cross sectionsThere are two ways to delete a single cross section:1. Right-click the center anchor point of the cross section in the map, and select "Remove Section" fromthe popup menu;2. Right-click the cross section name in the "Project Explorer" and select "Remove Section.To delete all cross sections, right click the "Sections" folder in the "Project Explorer" and select"Remove All...". After confirmation, all cross sections will be removed from the project. 4.14 Cross Sections from CADCross Sections from CADInstead of placing cross sections by hand, it is also possible to import them directly from an AutoCadDXF project.To use this method, please make sure you use a separate AutoCad layer for these lines.ImportTo start importing the line data used to create sections, select the "Generate sections from DXF..."option by right clicking the "Sections" folder in the project view.If the project view is not visible, you can show it by selecting "Project Explorer" from the "View" menu.Eye4Software Hydromagic 6.096© 2014 Eye4Software B.V.FileFirst, you have to click the "Browse..." button to select a CAD file. At this moment, only AutoCad DXFfiles are supported.If your AutoCad file is in DWG format, you can export it to DXF by using the DXFOUT command inAutoCad.When a valid file has been selected, the layer names will be loaded and displayed in the dialog.Map display / Background maps 97© 2014 Eye4Software B.V.Select LayersAfter the file has been loaded, you have to check the layer(s) containing the line data used to generatedsections.You can select one or more layers, please note that only LINE and POLYLINE entities will be converted.Eye4Software Hydromagic 6.098© 2014 Eye4Software B.V.Original DXF file, layer to be imported is colored blueOptionsIt is possible to change the prefix of the section names, as well as a clipping area. When a clipping area(boundary) is selected, all lines will be clipped within this area.When clipping area is set to "N/A" all lines will be loaded "AS IS".Starting ImportTo start creating lines, just click "OK". After a few seconds you will see the imported lines in yourproject.Map display / Background maps 99© 2014 Eye4Software B.V.Sections generated from DXF file shown above4.15 Channel DesignChannel DesignAfter placing cross sections, as discussed in the previous chapter (Cross Sections), we need to set thedepth or elevation information of a couple of coordinates along the cross section. These values are stored as pairs of distance and level data, where distance is the distance measuredfrom the start of the line. In order to create a theoretical DTM to be used in volume calculations, we need these values.When the depth and the slope of the shore are known, it is possible to calculate depths on the crosssections automatically.Calculating profilesTo alter a cross section's profile, just right click on the center anchor point, and select "Edit Section...".The following dialog ("Edit Cross Section") should now appear: Eye4Software Hydromagic 6.0100© 2014 Eye4Software B.V.When first editing a cross section, you will notice the graph display is empty, this is because no depthsare stored by default. In this example, we will create a channel with a depth of 5 meters and a slope of50 percent. This means, that for each 2 meters, the bottom depth increases with 1 meter. When thebottom depth increases with 1 meter for each 4 meter extra distance from the shore, the slope is 25%.To calculate profiles from this setting, click the "Auto..." button. The following dialog should now appear: Map display / Background maps 101© 2014 Eye4Software B.V.In the left section of the dialog, you can enter the channel design parameters, in the right section, youcan select the cross sections you want to apply these parameters to. In this example, the depth at theshoreline should be half a meter, at the waterway axis, the depth should be 5 meters. The slope used is50 percent. Click the "OK" button to apply these settings. The graph display will now look like this: You can check the other sections by browsing through them using the next and previous buttons. Manual editingIn cases where calculation is not usable, for instance when a different slope is used on either sides, orwhen a section is not placed between shores, you have to enter the distance and depth valuesmanually. To do so, click the "Edit..." button to open the profile editor: The table at the left of the dialog allows you to alter, insert and delete the distance-depth pairs if theEye4Software Hydromagic 6.0102© 2014 Eye4Software B.V.profile. Changes made, are directly visible in the graphical display. When done, just click "OK" Checking the profilesThe quickest way of checking whether al profiles have been created correctly, is by creating a matrixview using the cross sections. To do so, select the "Generate Matrix..." option from the "Sections" folderin the "Project Explorer". Select the correct boundary (in most cases the boundary used for auto placement of the sections), afilename for the matrix, and the spacing used (can be larger for a test, for volume calculation, use thesame spacing as the matrix created from the sounding). Click "OK" and check the result. Map display / Background maps 103© 2014 Eye4Software B.V.5 Recording Data5.1 Getting StartedIntroductionSince Hydromagic Survey version 6.0, sensor data isn't recorded directly to a sounding file, like it usedto be in for instance, version 5.2.All sensor data is now time tagged with millisecond accuracy and stored into a plain ASCII text file.Advantages of using raw data filesTime TaggingIn a sounding, position values are combined with depth measurements and eventually motion and tidecorrection data.Because data isn't arriving at exactly the same time, the offset between a depth and position reading hasto be calculated.This is done when generating a corrected sounding file from a raw data file using the "Generate SoundingWizard".LatencyIn hydrography, latency is the time elapsed between sending out a ping by the echosounder, and thetime the serial data with the depth value is received at the computer's serial port.When this value is known (usually between 10 and 100 milliseconds), the delay is subtracted from therecorded timestamp to get an even better accuracy.The higher the speed of the vessel during a recording, the bigger the error because of latency will be.When you are not able to apply latency corrections, don't go to fast Data SecurityEye4Software Hydromagic 6.0104© 2014 Eye4Software B.V.Because the raw data is never altered after you complete recording data, you will never loose any databy performing invalid corrections to your data.Just use the "Generate Sounding Wizard" again to edit your original data and create a sounding filewhich can be used for further processing.Data EditingEye4Software Hydromagic keeps two copies of the raw data files on file. One copy is the original data,which is never altered, and the second one is the modified data.You can alter the modified raw data over and over again until your satisfied, and create a sounding filefrom it. If the data becomes corrupted, just revert back to the original data. 5.2 Creating a new singlebeam soundingCreating SoundingsBefore you can create a new sounding it is recommended to perform the following checklist: You have opened an existing or created a new project; Make sure the position is valid, and the GPS has good reception; Check whether a depth is indicated in the "Data View"; Check the echosounder offset (also known as static or fixed draft); When using a motion sensor, make sure it is tared; Check the PC's time and date, this is important when using tide correction; When using realtime RTK tide information, make sure the antenna offset and correct geoid modelare selected;Recording Data 105© 2014 Eye4Software B.V. It is recommended to enable the "autosave" function, please see below for more information.The next step is to load a background map, this is not required, but it can be used to check whetheryour position is still correct, and the software is still writing new soundings to the sounding.More information on importing or downloading background maps is covered in the Map display section ofthis manual.Recording Raw DataA sounding is created in two steps. First you are going to record raw data. All position, motion and depthdata is time stamped and stored into an ASCII file.The second step is to correct the raw data and generated soundings from it;Start RecordingWhen you are ready to start your survey, just click the "Record" button ( ) to start recording all sensordata to a newly created raw data file.Raw data files are generated every time you start a new recording. Raw files are named RAW0001,RAW0002, RAW0003 etc.To pause a recording without generating a new recording, just click the "Pause" button ( ) instead.When clicking the pause button again, the recoding will resume writing data to the same raw data file.You can record the complete area to a single file, or start a new data file for each surveyed line.Displaying raw data filesDuring recording, recorded raw data will be displayed on the map display. Please note, that at this stage only the uncorrected, unsynchronized raw depth (not elevation) andposition data is written to the display.Elevations and corrected values will only be displayed when the raw data has been converted to asounding.To change how raw data files are displayed (as track, positions or depth values), right click on the "RawData" folder in the "Project Explorer" and select the "Display Options..." option.A dialog box is presented allowing you to specify how all raw data files are displayed on top of thebackground map.Eye4Software Hydromagic 6.0106© 2014 Eye4Software B.V.Autosave optionTo prevent data loss, for instance due to a PC crash or AC power failure, it is recommended to use the"AutoSave" option. When this option is enabled all project data (including raw data and sounding files) will be saved at thespecified interval.To change the autosave option, select "Preferences..." from the "Options" menu, and click the"Miscellaneous" tab. You will see an "Auto save" section at the bottom of this window. Now click the"Setup..." button in this section. Enable the check box when you want to use autosave, and enter aninterval (minimum 1 minute). Click the "OK" button to apply the changes.Manually saving the raw dataRaw data can be saved at any time by just clicking the "Save" button in the toolbar ( ). It will be savedinto the "RawData" folder of your project.Recording Data 107© 2014 Eye4Software B.V.5.3 RTK TidesRTK TidesUsing a RTK receiver in fixed mode, you have X, Y and Z coordinates with an high accuracy ( < 2 cm ).Using the Z coordinate (also known as ellipsoidal height), you can calculate the current tide level in real-time, making it no longer necessary to have a tide gauge connected to the software, or to correct thesounding afterwards.RequirementsIn order to calculate tide levels in real-time, you need a RTK receiver with a valid correction signal.This correction signal can be provided by a GSM / GPRS ( NTRIP ) service provider, UHF base station oryour own base station on a known location.You also need a local geoid model. This is a file containing geoid - ellipsoid separation values for thearea or country you are performing your survey.Hydromagic ships with a couple of geoid models, including Belgium, the Netherlands and North America.If no geoid model is available for your area, please contact support.To perform the calculation, you also need to know the exact distance between the receiving element ofyour RTK antenna and the water surface.Receiver OutputTo retrieve the ellipsoidal height from your RTK receiver, it should have an NMEA0183 data output,supporting either the $GPGGA or $PTNL,GGK sentence as shown in the examples below: $PTNL,GGK,453049.0,0,3728.455440850,N,12215.253291068,W,3,9,2.0,EHT35.7424,M*Trimble proprietary message for RTK position $GPGGA,042629.00,3242.86076286,S,15133.15384408,E,4,12,1.1,6.573,M,26.799,M,1.0,0000*51Standard NMEA0183 sentence for GPS or RTK fix dataWhen the Trimble proprietary NMEA0183 message is used, the ellipsoidal height is provided directly inthe sentence, in the example above it is in the ellipsoidal height (10) "EHT35.7424" field.For standard NMEA0183, the ellipsoidal height is calculated from the M.S.L. (9) height and geoidalseparation (11) field. In this case the ellipsoidal height is calculated by using the formula below:In the example above, the ellipsoidal height is 6.573 + 26.799 = 33.372 meter. Ellipsoidal Height = M.S.L. Height + Geoidal SeparationEye4Software Hydromagic 6.0108© 2014 Eye4Software B.V.Formula for calculating ellipsoidal height from NMEA0183 GGA sentencePlease not that the M.S.L. ( Mean Sea Level ) height value returned by the GPS is calculated using theglobal EGM96 geoid model, and isn't accurate enough to use for your surveys.This is why you have to provide a local geoid model instead.RTK ConfigurationIn order to configure Hydromagic to use RTK tides, open the preferences dialog by selecting"Preferences..." from the "Options" menu.To view the RTK configuration, click the "RTK" tab. You should see following dialog:To enable tide calculation, you have to check the "Use Real Time Kinematic (RTK) for real time tidecalculation" box. When checked, you can alter the other configuration options.Recording Data 109© 2014 Eye4Software B.V.First you have to enter the height of the antenna above the water surface. Make sure to measure thisdistance as accurate as possible, an error in this measurement is directly converted to an error in thetide level. Secondly, select the geoid model used in your area by clicking the "Select..." button.For some area's it is possible to select a vertical reference, like NAVD88, NVGD29, M.S.L. etc.Please note that this setting is ignored for some countries.When finished configuring, just click "OK" to apply the settings.Testing RTK and geoid calculationsIn order to test RTK tide calculations, connect and power on your RTK receiver and make sure you havea valid RTK fix.The next step is to check the values in the "Navigation Data" window. If this view isn't visible, you canactivate it by selecting "Navigation Data" from the "View" menu.Eye4Software Hydromagic 6.0110© 2014 Eye4Software B.V.You have to check the following:The EHT (Ellipsoidal Height) is displayed in the data view. If missing, check the NMEA0183Recording Data 111© 2014 Eye4Software B.V.configuration of your RTK receiver.When using the Trimble proprietary NMEA0183 sentence, the M.S.L. field can be 0.00.You should have RTK Fix in the GPS Information section.The RTK tide value is displayed in green.Start recordingWhen the conditions above match, you can just start a new recording and proceed with your survey.When generating a sounding from your raw data files, you will be able to correct the tide settings ifneeded.6 Singlebeam Processing6.1 Getting StartedIntroductionIn Hydromagic Survey version 6.0 and higher, recorded data is stored as 'raw data files'.In order to create filtered, corrected and synchronized sounding data, which can be used to calculatevolumes, depth contours, digital terrain models and more, we have to process the previously recordedraw data files.The sounding wizardThe sounding wizard is one of the most important tools in the Hydromagic Survey software and allowsyou to convert one or more raw data files into something more useful sounding files.The wizard leaves the original recorded data intact and creates a second set of data files to track all thechanges you made.This method allows you to do corrections and filtering over and over again until you are fully satisfied withthe result.In case the data might become corrupted, just instruct the wizard to start over with the original raw data.Starting the sounding wizardAfter you recorded one or more raw data files, you can combine data from these files into sounding files.To do so, select the "Generate Soundings..." option from the "Tools" menu.The wizard will be displayed. You are now ready to create some sounding files.The first page of the wizard tells us what to expect in the few next steps.After quickly reading this information, just click "Next" to proceed to the next step.Eye4Software Hydromagic 6.0112© 2014 Eye4Software B.V.6.2 Selecting FilesSelecting FilesNext step is selecting the raw data files you want to process. By default all visible files are selected.The first time you are running the wizard on the files, the "Start editing from original raw data" option isselected.This means that you want to start editing the files from scratch. The second time you run the wizard, and you have made modifications, the "Continue editing modifiedraw data" option will be selectedand you can further process your modified files. If you want to start over with the original data, just selectthe "Start editing from original raw data" option.After selecting the files to process, click the "Next" button to proceed to the next step.Singlebeam Processing 113© 2014 Eye4Software B.V.Modified DataPlease note that the original recorded raw data is never altered. All modifications are stored as a copy inthe "Modified" folder of your projects folder on the hard disk.When you choose to start editing from the original raw data, the modified data of the previous sessionswill be overwritten.6.3 Tide CorrectionTide correction settingsThe next step in the conversion process is to define how the sounding is corrected for tides.If you do not want to use tide corrections, for instance when calculating volumes, you can skip this stepby selecting the "Do not use tide corrections" and clicking the "Next" button.Eye4Software Hydromagic 6.0114© 2014 Eye4Software B.V.Tide GaugesIf a tide gauge receiver is used, you can select the "Use tide gauge measurements" option.The software will use the tide observations stored in the raw data file.Use ellipsoidal height as returned by the RTK receiverUse this option when a geoid model has been loaded into the RTK receiver.The software will use this calculated height directly without further corrections.Use tide correction fileWhen you want to use tide corrections without special hardware such as a RTK receiver or tide gauge,you should select this option.It allows you to create a tide correction file where you can enter the tide observations made during thesurvey.You can start the tide editor by clicking the "Editor..." button. Once completed, save the tide file andselect it using the "Browse..." button.Tide File EditorThe tide file editor can be used to alter previously saved tide files, or to create a new tide file.To start the tide file editor, just click the "Editor..." button. The following window should appear:Singlebeam Processing 115© 2014 Eye4Software B.V.Use geoid modelWhen a RTK receiver in fixed mode is used, the height of the antenna is stored into the raw data file asellipsoidal height.By applying a geoid model and an antenna offset, you can calculate the exact tide level for each RTKposition stored in the file.6.4 Draft and Sound VelocityDraft and sound velocity correctionsIf you are not going to use either draft or sound velocity corrections, make sure both check boxes areunchecked and click "Next".Keep reading if you want to use one of these corrections.Eye4Software Hydromagic 6.0116© 2014 Eye4Software B.V.Sound velocity correctionsAn echosounder calculates depth by sending a pulse and measuring the time it takes to get to theocean floor and back.With this time and the speed of sound through the water, the depth is calculated. For fresh water, the speed of sound is 1500 meters per second, however, for salt water this speeddepends on the salinity, temperature and depth.Using the sound velocity correction option you can correct your sounding for salt water. Please do notuse this function if this correction is already used in the echosounder.Singlebeam Processing 117© 2014 Eye4Software B.V.Dynamic draft correctionsDynamic draft corrections can be used to correct the downwards motion of the ship.For instance, when using a speedboat, you may notice that when the speed increases, the rear of theship lowers while the front raises.This is what we call dynamic draft, and depends on the speed. You can correct for this motions bycreating dynamic draft correction table (speed versus draft).Eye4Software Hydromagic 6.0118© 2014 Eye4Software B.V.6.5 Correcting DataCorrecting dataThe last step we have to perform before data gets converted to a sounding, is to correct the data.We have to filter out spikes, out of range data and invalid position data.Hydromagic offers multiple tools to correct your data:Echogram EditorPosition Data EditorTable EditorData Filter6.5.1 Filter DataFilter DataThe filter tool can be used to filter out unwanted data. You can use it to delete zero (invalid) soundings,position data measured with a low DOP, invalid motion sensor data and more.Singlebeam Processing 119© 2014 Eye4Software B.V.Configuring filter optionsPosition dataThis option can be used to filter out unreliable position data, for instance when the GPS fix wasn't RTKfixed, or the DOP was to high.Check the "Filter position data" checkbox, and fill out the fields.Depth dataIt is recommended to use this option before the echogram editor, because you can use this to filter outspikes and zero values.Just check the "Filter depth data" checkbox and enter the minimum and maximum expected depth forEye4Software Hydromagic 6.0120© 2014 Eye4Software B.V.the low and high frequency soundings.Motion dataYou only need this feature when using a motion sensor for pitch, roll and heave.Check the "Filter motion data" checkbox and enter the maximum angles for pitch and roll, and theexpected range for the heave corrections received from either the echosounder or motion sensor.Skip this option when no motion sensor was used during the survey.Start FilteringWhen all options have been configured, just click the "Apply" button to start the filtering process.When one of the filters has been applied, a new modified raw data file is written in the "Modified" folder inyour project root.6.5.2 Echogram EditorEchogram editorThe echogram editor is used to quickly remove spikes and void data from a sounding.To start the echogram editor,just click the "Start..." button in the "Edit echogram(s)" section.Using the echogram editorUsing the echogram editor is very simple. Just select the data you want to remove and click the removebutton (C).It is also possible to edit or delete single values using the mouse. You can edit either the low or highfrequency depths with this tool.When done editing the echogram, click the "OK" button to save your changes. To discard, click "Cancel"When an echogram has been altered, a new modified raw data file is written in the "Modified" folder inyour project root.Multiple FrequenciesThe echogram editor allows you to modify both low and high frequency depth measurements.Singlebeam Processing 121© 2014 Eye4Software B.V.When dual frequency is selected, you can select both low and high frequency spikes or data for deletion.When you have problems deleting either low or high frequency data when values are very close toanother, just switch to single frequency mode using either the "Low Frequency" or "High Frequency" option.Echogram editor toolbar(a) - Remove SelectionTo remove spikes and zero value, you can select the data by holding the right mouse button.When the invalid data has been selected, click this button to remove it from the data file.(b) - Reload EchogramReload the echogram from disk(c) - Undo operationUse this button when you removed data by accident.

Using the name prefix youcan add a prefix to the file name.For instance, when the name prefix is set to 'SNDG', a raw file named 'RAW0006' will be names'SNDG0006' after conversion.Record intervalThe interval at which soundings are calculated. You can use a timed interval or use the same interval atwhich the GPS or echosounder sends its data.The interval depends on the resolution needed and the size of the area. When a raw data file covers avery large area (>100.000 soundings) it is better to use a lower interval, for instance one second.Using a very small interval on large data files may slow down other post processing utilities.Overwrite existing filesUsing the wizard it is possible to generate a sounding file over and over again until you are satisfied withall settings and corrections.Checking this box will omit a warning message when you are about to overwrite a previously generatedsounding file.Generate soundingSinglebeam Processing 129© 2014 Eye4Software B.V.When ready, click Finish. After a few seconds, depending on the amount of data, the wizard closes andthe generated soundings will be visible in the project explorer.From now on, the sounding is also available as a human readable ASCII file in the "Soundings" folder ofyour project.In this example, with the interval of the records set to 0.25 seconds, your sounding should look like thiswhen opened in the sounding editor:To get more information on a single sounding record (we also call this a single ping in Hydromagic), justdouble click the row you want details on:Eye4Software Hydromagic 6.0130© 2014 Eye4Software B.V.6.7 Importing SoundingsIntroductionThe ASCII import function allows you to import soundings written in ASCII format. For instance, to importa sounding exported from another Hydromagic project, or created with other software. Please note that because this imported data is not time tagged, you can not correct this data for tidesand latency using the "Generate Soundings Wizard" Importing sounding dataSinglebeam Processing 131© 2014 Eye4Software B.V.The ASCII import function allows you to import soundings written in ASCII format. For instance, to importa sounding exported from another Hydromagic project, or created with other software.Open the "Import ASCII Data" dialogThe dialog can be opened by selecting "File"=>"Import"=>"Import ASCII Data..." from the main menu.The following dialog will appear:Select input fileClick the "Browse..." button to select the file to be imported. All files will be displayed, there is no fileextension filter applied. Some file extensions that are commonly used for ASCII files include: *.ASC,*.TXT, *.LOG and *.CSV. The imported file is never modified by this software. This dialog can also beused to import boundaries, grids and waypoints. Make sure the "Load data as" options is set to"Sounding".Field SeparatorThis value is set to "Auto" by default, which means that the software will try to detect which character isused to separate the fields in the ASCII file.In most cases you do not have to adjust this value.Eye4Software Hydromagic 6.0132© 2014 Eye4Software B.V.Skipping lines and fieldsIn cases where the data does not start on the first line of the file (for instance, when header names arepresent), you can skip these lines by increasing the "Number of lines to skip value".The "Number of fields to skip option" can be used in cases where there are fields before the actual XYZdata, for instance, record Id's.You can use the "View" button to check if these options apply to your input file.Coordinate field orderThis option is to set the order of the fields in the file. The following is supported: Latitude, Longitude; Longitude, Latitude; Northing, Easting; Easting, Northing;When a third field is present in the file, it will be interpreted as depth. Most software stores soundings in XYZ format, so selecting "Easting, Northing" here would probablywork in most cases.Coordinate field formatWhen the input files contains values in geographic format (i.e. latitude and longitude), and thecoordinates are stored in degrees, minutes and seconds format, or degrees and minutes format, set thisoption to the correct value.When coordinates are stored in decimal values, leave the "Decimal" option selected.Projection and UnitsThe software needs to now which projection is used in the file (only when Northing and Eastingcoordinates are used instead of Latitude and Longitude), so it can be referenced to WGS84 coordinates.When an altitude or depth is present in the file, you also have to set the unit used (meters or feet).Importing the fileJust click "OK" to start reading the file. When all parameters were entered correctly, the importedsounding will appear in the "Project Explorer". 6.8 Importing Soundings from NMEA0183 logNMEA0183 LogfilesThis feature allows users to create a sounding directly from a recorded NMEA0183 logile. This can beused to retrieve data from, for instance a remote controlled survey vessel such as the OcienScience Z-Boat 1800.This option can only be used when depth and position data is in the same file. Please note that becausethis imported data is not time tagged, you can not correct this data for tides and latency using the"Generate Soundings Wizard" Singlebeam Processing 133© 2014 Eye4Software B.V.NMEA0183 Import ToolTo start the NMEA0183 importing tool, select "Import NMEA0183..." from the "File" => "Import" menu asshown below.In order to import data, you have to specify a local map projection first.

When all parameters were entered correctly, the exported fileshould appear in the folder you selected.7 Post Processing7.1 Generate and Display MatrixIntroductionIn Hydromagic, a matrix is a collection of regularly spaced depths, which can be projected over the mapas color or text. This is also known as a digital terrain model or DTM.During the generation of a matrix from a sounding, the scattered data points are converted to regularlyspaced data using a TIN (Triangulated Irregularly Network). This TIN is generated using a Delaunay triangulationalgorithm.All new data points are generated by "filling" the triangles, which have been formed from the scattereddata. The image below shows a color matrix which has been generated using TIN (data points at 0.25 meterinterval). Eye4Software Hydromagic 6.0138© 2014 Eye4Software B.V.Generating a matrixTo generate a matrix, you must have loaded either a valid sounding or a shoreline containing depth orheight information. Without sounding or shoreline data, it is not possible to generate a matrix.In order to generate the matrix, you have to specify some settings. To do so, open the "Generate Matrix" dialog by selecting "Generate Matrix..." from the "Tools" menu:Post Processing 139© 2014 Eye4Software B.V.Sounding dataSelect from which sounding(s) you wish to generate the matrix. By clicking the "Select..." button, youwill be able to select one or more soundings that will be used to calculate the triangulation from which the matrix or digital terrain modelwill be generated.Shoreline dataSelect which shorelines you wish to include in the matrix calculation. Shorelines can be used to append extra data near the shoreline, or to clip the matrix data along theshore.For more info on how shorelines can be used, please refer to the chapter "Entering Shoreline Data'".Sounding channelYou can use this setting to select which data of the sounding is used to generate the matrix.This can be one of the following values:Depth recorded with the low frequency channel of your echosounder;Depth recorded with the high frequency channel of your echosounder;The difference in depth between the high and low frequency channel (Low - High);The difference in depth between the high and low frequency channel (High - Low);Sensor data channel 1;Sensor data channel 2;Sensor data channel 3;The sensor data channels can be used to store either magnetometer data, information on reflectivity,bottom loss or duration of the returned echo(s).The data that each channel contains can differ, and depends on the echosounder plugin that was used toEye4Software Hydromagic 6.0140© 2014 Eye4Software B.V.record the data.Matrix spacingYou can select the spacing of the regularly spaced data here. The same spacing is applied to both the Xand Y axis. The spacing has to be entered in the same units as used for the map projection.Which spacing to use depends on the zoom scale you are using. For an overview of a large area, youcan use 2.5 meter. When zooming in on a smaller area, the best is to use values between 0.25 and 1.00 meter. Please note that when using a larger spacing, it will be generated and displayed faster then a moredense matrix.Clipping areaUse this to select which clipping area (boundary) has to be applied when generating the matrix. Onlydata points within this area will be calculated. This can be used in cases when only a part of the sounding areas has to be interpolated. When noboundary is selected, the matrix is only clipped by the extends of the data points.In addition to boundaries, you can also use shorelines to clip data along the shore, or to generate islands(or holes).Output file nameEnter the name of the file that is generated here. This setting is required. You can enter a simple name (for instance the same name as the sounding used) here, which will bestored in the default matrix folder. When you want to store the result elsewhere, use the browse button to select the output folder and filename. The data will be added to the current project and stored in a separate ASCII XYZ file at the desiredlocation.Generating the matrixFinally, click the "OK" button to start the process. It should take a couple of second, you can watch theprogress in the status bar of the main window. After generation, you will notice the matrix has been added to the project. Depending on theconfiguration, the newly generated matrix will be drawn over the map. Displaying the matrixThere are more ways of showing the matrix on the map. In the example near the top of this page, it isdisplayed at both colors and text at a 5x5 meter interval. It is also possible to not show it (and just use the matrix to export data), to show it with colors only(using the defined color ranges) or to show its depths as text.To change settings on how the matrix is shown, right click the "Matrices" folder in the "Project Explorer"and select the "Display Options" option from the popup menu.A dialog with all matrix settings will be displayed. It should look like the screenshot below:Post Processing 141© 2014 Eye4Software B.V.Display MatricesUsing this checkbox you can toggle the displaying of matrix files on the map.When matrix display is disabled, all other options will be disabled.Display matrix as colorsWhen enabling this option, the matrix is displayed as a color grid on top of the map. The "Colors..." button will also be enabled, so you can start creating the color ranges for your sounding.Display matrix as depthsInstead of drawing the matrix as a color grid, you can also choose to draw depth values at fixed intervals.Depending on the size of the matrix, you have to adjust the text intervals in a way that the text's on themap do not intersect. The text spacing can be set in horizontal and vertical direction separately.Display text as colorsWhen this option has been checked, text is drawn in color, indicating the depth range.You cannot combine this option with the "Display matrix as colors" option.Color RangesEye4Software Hydromagic 6.0142© 2014 Eye4Software B.V.In this dialog, you will be able to add, remove or modify color ranges by clicking one of the buttons at thebottom of the list. To change a range, just double click on it, and change the settings. In case you wantto store the color scheme you designed for other projects, you can store it in a separate XML file usingthe "Save..." button. Just use the "Load..." button in the other project to retrieve this scheme.Display color legendThe second section contains the settings for the color legend which is displayed as map overlay whencolors are displayed. You can turn it on or off here.Generate color rangesPost Processing 143© 2014 Eye4Software B.V.It is also possible to create a color scheme using a min, max and step value. To do so, select the "Auto..." button, and select the lower and upper range, next specify the intervalbetween the ranges. This tool will generate max 30 ranges, so it is important to choose the correct interval.7.2 Generate Matrix from SectionsGenerating a reference matrix from sectionsA reference matrix that can be used to perform volume calculations can be created from:a recorded sounding;collection of sections, also known as channel design;a vector chart which contains 3D vectors.Channel DesignWhen comparing the matrix created from a sounding with a matrix created from a channel design, wecan calculated the amount of material which has to be (re)moved in order to get the result as in thechannel design.Eye4Software Hydromagic 6.0144© 2014 Eye4Software B.V.Generate the matrixTo start creating a matrix from the channel design, right click on the "Sections" folder in the "ProjectExplorer" and select the "Generate Matrix..." options as shown below:After selecting this option the "Generate Matrix from Sections" will be displayed, as shown in the imagebelow:Post Processing 145© 2014 Eye4Software B.V.SectionsSelect which sections you want to include in the matrix calculation.

During the generation of contour lines from a sounding, the scattered data points are converted toregularly spaced data using a TIN (Triangulated Irregularly Network). This TIN is generated using a Delaunay triangulationalgorithm.After this step, Hydromagic calculates the contour lines by determining the positions where the depthcontour crosses the calculated triangles.All these lines are connected to each other, and stored as a vector layer, which can be exported aseither an ESRI shape file or AutoCAD DXF file.Creating ContoursTo generate contours, you must have loaded either a valid sounding, or a shoreline containing depth orheight information.Without sounding or shoreline data, it is not possible to generate depth contours.Soundings without valid depth or elevation data will be ignored. If you want to clip the generation ofcontours to a specific area, you should have created or loaded a boundary as well.Open the "Generate Contours" tool, by selecting it from the "Tools" menu. The following dialog willappear:Post Processing 151© 2014 Eye4Software B.V.Sounding dataSelect from which sounding(s) you wish to generate the depth contours. By clicking the "Select..."button, you will be able to select one or more soundings that will be used to calculate the triangulation from which the depth contours will begenerated.Shoreline dataSelect which shorelines you wish to include in the depth contours calculation. Shorelines can be used to append extra data near the shoreline, or to clip the depth contours along theshore.For more info on how shorelines can be used, please refer to the chapter "Entering Shoreline Data'".Sounding channelYou can use this setting to select which data of the sounding is used to generate the contours.This can be one of the following values:Depth recorded with the low frequency channel of your echosounder;Depth recorded with the high frequency channel of your echosounder;The difference in depth between the high and low frequency channel (Low - High);Eye4Software Hydromagic 6.0152© 2014 Eye4Software B.V.The difference in depth between the high and low frequency channel (High - Low);Sensor data channel 1;Sensor data channel 2;Sensor data channel 3;The sensor data channels can be used to store either magnetometer data, information on reflectivity,bottom loss or duration of the returned echo(s).The data that each channel contains can differ, and depends on the echosounder plugin that was used torecord the data.Clipping areaWhen a clipping area has been specified (by using a earlier created boundary), the contour lines will beclipped at the point they cross the polygon of the boundary. This way it is possible to only generate contours in a specified area. When the "No Clipping" option isselected, there will be no clipping and the contours will cover the entire area of the sounding.In addition to boundaries, you can also use shorelines to clip shorelines along the shore, or to generateislands (or holes).Contour levelsYou can generate contours using a fixed level, or use color ranges. You can also combine the twooptions. Using a fixed level can be useful, to display a reference line (for instance the dredging depth) tosee what's above and below this line. When using the color ranges, the levels displayed as colors will beaccentuated.Contour smoothingWhen generating depth contours from a TIN model containing large triangles, it happens often that sharpedges appear in the contour lines.To make the lines look more pleasant for the eye, you can enable the "Use contour smoothing" option touse a B-Spline algorithm to smoothen the lines.The level settings allows you to set the degree of smoothing. When using level 1, just a little bit ofsmoothing is applied, while level 9 applies the most.A good value to start with is level 5. When contours are starting to cross, you might want to try a lowerlevel.Layer nameThe layer name can be edited to allow you to create multiple layers, for instance, a separate layer fordifferent fixed levels. Using the project manager, you can select which contours are visible or not.File nameThe generated contour lines can be directly written to an ESRI shape file. To do so, enter a file name intothis box. When the contour is not written to a shape file, it is volatile and will be lost once the project isclosed and reloaded.FinishWhen all settings are correct, click the "OK" button to finish the process. The software will now createPost Processing 153© 2014 Eye4Software B.V.the TIN model, and generate the contour lines. You will have to wait a couple of seconds, depending onthe number of records your sounding contains. When ready, the dialog will disappear, and the contoursare drawn on the screen.Managing ContoursShow / Hide contoursTo temporary hide or show a collection of contour lines, just click the "eye" icon in front of the contourname. When hidden, the contour is still loaded, but just not shown on the screen.Delete contoursTo delete a collection of contour lines, look for the name in the "Project Explorer" and right click on it. Select the "Remove Map..." option from the popup menu, and confirm the action.Export contoursEven when you choose to not save the contours when creating, it is possible to export them afterwards. From the "File" menu, select "Export", then select the "Export Vector Data" option:Eye4Software Hydromagic 6.0154© 2014 Eye4Software B.V.7.5 Volume Calculation (Matrix)Volume calculation using matrixThe matrix volume calculation tool can be used in two ways: to calculate the difference in volumebetween two matrices (for instance, pre-dredge and post-dredge), or between a matrix and a fixed level. This last option can be used to calculate the area and volume of a pond or basin or tank. In order to usethis option for volume calculation, make sure you have converted your corrected sounding to a matrix(see chapter "Generate and Display matrix" ).This tool calculates volumes by multiplying the difference between depth in matrix 1 and matrix 2 withthe size of a single cell (Spacing).Volume calculation toolTo start the matrix volume calculation tool, select the "Volumes (Matrix)" option from the "Tools" menu.The following dialog will be shown:Post Processing 155© 2014 Eye4Software B.V.Matrix 1Use this setting to specify the matrix created from your sounding, or when using two matrices, thematrix created from the post-dredge sounding.Matrix 2Use this setting to specify the matrix created from your pre-dredge sounding or a matrix created from a3D cad file or channel design.In case you are calculate the volume of a basin or pond, select the "" option, andenter the level of the water surface. When no tide correction is used, this value is 0.00.TotalsThis section will display the total area and volume for the whole sounding.The processed area means the amount of overlap between the two matrices used.When a fixed level is used, the overlap is always 100% and the processed area will be the same as thetotal area.Eye4Software Hydromagic 6.0156© 2014 Eye4Software B.V.Below ReferenceArea and volume below the level found in Matrix 2Above ReferenceArea and volume above the level found in Matrix 2CalculateClick the "Calculate" button to calculate area's and volumes from the selected matrices.Calculated values are split in totals, above reference (Matrix 2) and below reference (Matrix 2).ReportClick the "Report" button to calculate area's and volumes from the selected matrices.This function creates an ASCII file containing a detailed report on the calculated volumes, which can besaved or printed.Post Processing 157© 2014 Eye4Software B.V.

When finished, just click theright mouse button to store the line.Shorelines will appear as green lines on top of your background map(s).Post Processing 159© 2014 Eye4Software B.V.Entering ManuallyWhen you want to enter the shoreline manually, for instance when you have measured the shorelinecoordinates from the shore using a RTK rover, right click on "Shorelines" in the "Project View" and select"Add Shoreline".The following dialog should now appear, allowing you to enter all measured coordinates in thespreadsheet. Click the "Add..." button to add new records.Eye4Software Hydromagic 6.0160© 2014 Eye4Software B.V.Setting depth valuesWhen the shoreline connects points with the same depth value, for instance zero, you can set all Zvalues at once by clicking the "Level..." button and entering the value. Post Processing 161© 2014 Eye4Software B.V.Modifying shoreline dataTo modify the positions in shoreline data, you can use the mouse to drag and drop the positions on themap.When you want to modify positions manually, or you want to alter the depth values, you have to use the"Edit Shoreline" dialog.To open this dialog, right click on the shoreline you want to modify in the "Project View" and select the"Edit Shoreline..." option.Eye4Software Hydromagic 6.0162© 2014 Eye4Software B.V.Applying shoreline dataShoreline data can be used when generating matrices, and thus also calculating volumes (usingmatrices).When generating a matrix, you can specify which shorelines you want to include by clicking the"Select..." button.In the dialog that appears, check the shorelines you want to include and click "OK":Post Processing 163© 2014 Eye4Software B.V.7.7 Export to Google EarthIntroductionKML (Keyhole Markup Language) is an XML format used by Google Earth to load overlays. KML cancontain point, poly line and polygon data, as well as one or more references to raster overlays. It is alsopossible to script complete Google Earth presentations into a KML file. At this moment, Eye4Software Hydromagic supports point, line and polygon features, as well asattributes, styles and ground overlays. Eye4Software Hydromagic is able to both import and exportGoogle Earth KML files. This document describes how to export them.Exporting DataIn Hydromagic, it is possible to convert tracks, vector maps, matrices, boundaries, comments,waypoints and sections to KML files.When exporting a matrix, an image file is generated and loaded in Google Earth as a so called "groundoverlay".To start exporting data, select the "Export KML Data" from the "File" => "Export" menu as shown below:Selecting data to exportEye4Software Hydromagic 6.0164© 2014 Eye4Software B.V.In the dialog that appears, you will see a list of all items that can be converted to KML.Just check the items you wish to export. By default, all visible items are selected. To reset the selection, click "Select None", to select all items, click "Select All".Select output fileThe next step is to select a location to store the exported data. You can save the data as KML or KMZfile. Click the "Browse..." button to open a save file dialog, and enter the name for the file. In the save filedialog, you can also choose between the "KML" or "KMZ" formats. When you choose to export a matrix,the file extension will default to "KMZ" which allows you to store the KML and image data into a singleKMZ file.Post Processing 165© 2014 Eye4Software B.V.KML FormatWhen using the KML file format, a KML file is generated as well as an image file (PNG) for eachexported matrix. The image files are stored in the same folder as the location of the KML file.When not exporting matrices or large amounts of vector data, KML is probably the best option for you.KMZ FormatIf you are going to export matrices, or large amounts of vector data, KMZ is the best choice. A KMZ file is a zipped archive containing a main KML file (doc.kml) and, in case of exporting image datasuch as matrices, some image files.When using the KMZ file format, you can always transfer the data by distributing a single KMZ file.Exporting the dataJust click "OK" to start the export. For small files, this takes only a couple of seconds, for large projectsit can take a couple of minutes. You can watch the progress in the status bar at the bottom of thescreen.

You can also choose to export onlythe depth information by selecting the "Do not export a map" option.Please note that not all background maps can be exported to AutoCAD DXF. Only vector charts like S57ENC, ESRI ShapeFile, DXF, Microstation DGN and ARC/INFO can be used.MatrixThe matrix can be selected using the second selection box. In case you want to export the map only,you can select the "Do not export matrix" option here.FilenameIn the third input field, you have to select the file name of the CAD file to be generated. This file should bea valid file name at an accessible location with the extension ".DXF".OptionsWhen your background map contains a lot of text, it is recommended to turn off the "Export Map Texts"function, to prevent the map text from interfering with the depth values.If needed, you can write the DXF file using another local grid by changing the grid displayed at thebottom of the window. By default, the current local grid is used.Starting the export processWhen all parameters are setup correctly, click "OK" to start the export. A progress indicator will appearat the bottom at the screen, and the window will close after a couple of seconds.You can now open the DXF file in most CAD programs, it is also possible to use the generated DXF fileas a background map in Hydromagic.Opened in a CAD editor, the result will be (depending on your settings):Opened in QCadEye4Software Hydromagic 6.0170© 2014 Eye4Software B.V.Opened in Hydromagic7.9 Export current viewIntroductionUsing the Eye4Software GPS Mapping Studio, it is possible to save your current map view (includingoverlays like tracks, photos, comments, waypoints and routes) as an image file. The software can alsogenerate the world and projection files for you, so you will be able to load the image file directly in otherGPS or GIS mapping software, without the need to calibrated the map. For exporting, the following vectormap formats are supported: Graphics Interchange Format; Portable Network Graphics; JPEG Image Files; Tagged Image Format Files; Windows Bitmap Files.Loading the source dataIn order to load the map, used as background, select "Import" => "Import Map..." from the "File" menu.Because the map is just exported as an image file, all formats can be used. Please not that attributeinformation is not saved on export, because a simple image format is used.After loading the map, you can add overlays, like photos, comments and waypoints. To import suchoverlay data, select "Import" => "Import GPS Data..." from the "File" menu. Hydrographic data such as soundings, matrices, cross sections and boundaries will also be visible in thePost Processing 171© 2014 Eye4Software B.V.exported final product.Exporting the viewIn order to export the current map view, select "Export" => "Export Current View..." from the "File"menu. Export Current View DialogAfter a few seconds (needed to capture the image), the following dialog will appear: Eye4Software Hydromagic 6.0172© 2014 Eye4Software B.V.Output fileFirst, you have to select the output format and the filename of the image file. After selecting the format,use the "Browse..." button to select the folder and file name.Generate World FileIn cases where you want to import the exported image file into another GPS or GIS mapping softwareproduct, you have to enable this option. The software stores the upper-left coordinates and the pixelsizes (scale) in the world file. Depending on the image format you are using, the world file will have thefollowing file extension: GIF World File - gfw; PNG World File - pgw; JPG World File - jgw; TIF World File - tfw; BMP World File - bpw;3.72671500-3.726715242435.599588476855.346680sample world fileProjection FilesThe software can generate a ESRI WKT or PROJ.4 projection file for you. Together with a world file forgeo-referencing the image, this enables the screenshot to be imported in most GPS/GIS softwarepackages.The generated projection file will always have the ".prj" extension, irrespective of the selected format.PROJCS["Amersfoort / RD New", GEOGCS["Amersfoort", DATUM["Amersfoort",Post Processing 173© 2014 Eye4Software B.V.
