Redesigned to Improve Efficiency

The 2016 version introduced a completely redesigned interface to streamline workflow and to provide easy access to the important components of the application.

The all-in-one interface of Geographic Calculator enables users to complete a number of geodetic and geospatial transformation functions on various types of data in the same interface with unmatched accuracy and accountability. The enterprise collaboration tools such as workspaces and network folders enable consistency and repeatability of highly accurate data translation across your organization.

For new users, a consolidated Start Page provides clear and concise explanations for each type of calculation and serves as a launching pad for easy access to the various jobs. Reorganized menus and updated toolbar buttons have been implemented to facilitate efficient data processing. The Point Database Conversion job has been split into five logical components: Conversion; Forward/Inverse Calculation; Scale and Translate; Best Fit; and Derive Datum Shift. This simplified approach provides a unique and intuitive interface for each type of calculation. The highlight of the 2017 release is the introduction of a new Seismic Survey QC Job for checking the quality of preplot and poststack seismic lines between UKOOA and SEG-Y files.

Blue Marble Desktop

Since 1993, Geographic Calculator has been the coordinate conversion tool of choice for GIS and survey professionals around the world. The software quickly grew in popularity over that first decade and has maintained its reputation as the best coordinate conversion solution on the market. Geographic Calculator has come a long way since then with many improvements over the years. In 2004, the underlying GeoCalc library was re-written and in 2007 a new version was released as the Blue Marble Desktop.

2013 saw a rebranding of the Blue Marble Desktop to Geographic Calculator. Blue Marble incorporated all of the functionality of the desktop including the Geographic Transformer, Translator and Spatial Connect products into Geographic Calculator. This did away with the confusing versioning and introduced an easier-to-follow annual naming convention with one or two service pack updates between releases.

Interactive Conversion
Select your source and destination coordinate systems, enter your coordinates, choose the datum transformation you would like to use, and then press the 'Calculate' button. Yes, it's that easy! The Interactive conversion tab allows you to convert, forward a position, and calculate the distance and azimuth between two points.

Point Database Conversion
A point database job allows you to perform coordinate conversion, forward and inverse and other calculations on your point database files. Work with flat files or files from a spatial database such as ArcSDE, Personal or File Geodatabase, Oracle Spatial and PostGIS spatial or ODBC databases like MS Access. With a given distance and direction, you can easily compute coordinates from an origin, or the distance and azimuth between points. Load in data from a variety of file types and output back to that file type or send your results directly to AutoCAD DWG/DXF files. A new search tool allows you to quickly search through the entries in your data. Manually specified transformations with Scale, Translation, and Rotation parameters are now supported in the Point Database Tab in addition to the Vector Conversion Job.

The point database tab has excellent support for Oil and Gas exploration specific formats like SEG and UKOAA. The interface is extremely fast and able to transform one hundred thousand records in 8 seconds or 50 million records in under an hour and a half. Users can easily work with large files by loading only a sample of the file to set up the job.

Additionally, you may:

  • Load an existing spreadsheet/database file in dBase v.3-5, Excel XLS v.2-2000, or ASCII text files.
  • Or use an ODBC Data Source to load data from Oracle, Postgres, SQL Server or another ODBC database. Spatial database support is available through our extension to ArcGIS. See below for more information.
  • Perform coordinate transformation on a variety of Oil and Gas industry formats: SEG-P1, SEG-Y, UKOAA P1/90, and SPS.
  • Right-click to modify the grid: insert, delete, clear and rename columns, and insert or delete a row.
  • Specify output coordinates display format.
  • Define custom text file formats, including custom header information.
  • Print the entire grid.
  • Save the point database in dBase, Excel XLS, ASCII text, MS Access, or as an AutoCAD DWG/DXF R12 map file.
  • You may read in and write out from and to any ASCII based format (not recommended for Oil and Gas formats).

Seismic Survey Conversion
The new Seismic Survey conversion allows users to access, maintain, and convert SEG, SPS and UKOOA formatted ASCII data faster and more efficiently. Quickly define custom reader rules to clean up improperly formatted data, convert multiple records types in the same file with a single pass, preserve and update metadata attached in all files and convert grid and geodetic record sets in a single pass.

Vector Data Conversion
Convert individual vector and CAD files, batch process an entire folder from different formats and coordinate systems - AutoCAD DWG/DXF, Microstation DGN, Esri Shapefile, ArcInfo Generate, E00, Google's KML, GML Simple Features, MapInfo TAB/MIF, Velocity files and much more are fully supported for both read and write. The Vector Data Conversion job includes area cropping and layer splitting functionality. Manually specified transformations for Scale, Translation, and Rotation parameters are also supported.

Land Survey Summary
The Land Survey Summary job allows users to generate printed layouts in Canadian survey systems. This allows users of Alberta and Saskatchewan lease data to plot layouts of points and lines directly from Dominion Land Survey coordinates in the context of the borders of the individual townships and ranges. Support has been added for Saskatchewan Grids systems, as well as enhanced layouts for non-square townships.    

Raster Format Support
Supports (read and write) all of the major GIS raster and reference formats including standard GeoTIFF, Mapinfo Table (TAB) and ESRI World (TFW, WLD, JGW) referencing files, Windows Bitmap (BMP), LizardTech's MrSID, JPG2000, Enhanced Compressed Wavelet (ECW), and more. Output from Raster Transform and Raster Mosaic jobs can be pipelined into other raster jobs, loading the data automatically.

Georeferencing - Reference Point Selection
Georeferencing is accomplished by applying affine or first through fifth order polynomial models to the reference control point information. Interactively add, delete, and edit reference information to ensure an accurate fit.

  • Easily georeference images by interactively selecting reference points
  • Multiple view windows enable rapid reference point selection within source images
  • Creates industry standard GeoTIFF, Mapinfo Table (TAB) and ESRI World (TFW, WLD, JGW) referencing files
  • Transfer control points directly from your ArcView, MapInfo, AutoCAD, and MicroStation map files
  • A production proven automatic reference point selection feature accelerates the registration of maps with regular grid lines

Raster Reprojection
Why would you want to reproject data with anything else? Geographic Calculator features the unmatched geodetic datasource of GeoCalc.XML. You can even define your own custom units, ellipsoids, datums and coordinate systems.


  • Over 3500 pre-defined coordinate systems
  • Over 165 ellipsoids
  • Over 630 datum transformations
  • Over 70 linear units and much more

Project Manager
Use the Project Manager to organize your Calculator jobs in one easy place. Save your jobs and share with your colleagues! Breathe easy; the days of re-creating the same project again are over. Here's a list of jobs you can perform to accurately manipulate your geospatial data time and time again.    

Administrative Tools

The Administrative Tools can be used either in a Single User or Network User context. These tools allow an administrator to set rules that restrict or assist users of various skill levels and job responsibilities with making selections from, and edits to, the Geodetic Data Source (geodata.xml). The Administrative Settings would typically be set by a skilled user in a management role. The Administrative settings are all found under Options>Administrative Settings. Settings available to the Administrative user are:

  • Password Access - Workspaces can be locked down to use only the settings applied in the other areas of the Administrative Settings.
  • Datasource Filters - Filters can be applied to the geodetic datasource to hide certain entries in the datasource from users. This feature can be used to provide a streamlined experience for users, or to keep users from choosing systems or transformations deemed inappropriate by an administrative user. The Filtering options allow an administrative user to determine which Projections, Horizontal Transformations and Vertical Transformations are visible to users.
  • Custom 'Areas of Use' - In addition to any Custom 'Areas of Use' setup by users, there are also the standard 'Area of Use' definitions contained within the datasource. Administrators can control whether both of these 'Areas of Use' types are applied.
  • 'Areas of Use' - Controls to determine whether 'Areas of Use' should be applied during coordinate transformation and object selection.
  • Datasource Validation - The Geodetic Datasource file with in Calculator exists as an XML database file called geodata.xml. This file can be edited outside the dialog, but it is not recommended. To prevent this, the geodata.xml file contains a digital signature that uniquely identifies the contents of the entire XML file. If the geodetic datasource is edited outside of the dialog, the digital signature will not match. An administrator can choose to validate the datasource on startup and alert users if the signature does not match.
  • Locking the Workspace - The default workspace can be locked so that users cannot overwrite it.
  • Locking the Datasource - To set all the Administrative Settings in place
  • Locking Spatial Databases - By default, Spatial Databases are locked down so that the user may not overwrite existing tables. An administrator can change this setting if desired.
  • Locking Text Schemes - By default, the custom text schemes used in the Point Database job are unlocked. This means that all users can create and modify formatted text schemes. To modify this setting, the administrator will need to login and check the Lock text file schemes from editing option in the Administrative Settings dialog.
  • Null Datum Transformations - By default, the Geographic Calculator allows conversions with no datum transformation. When the user selects from the list of possible datum transformations, will be one of the options. If is selected, there will be no transformation applied, and the result may not be accurate. To prevent this, administrators can select 'Do not allow null datum transformations' in the Administrative Settings.
  • Transformations that Affect Height - By default, Transformations with a vertical component will affect the outcome height or Z value. An administrator can change this setting if desired.
  • Disable 'Via Intermediate' Category - By default if there is no direct transformation between two chosen coordinate systems Calculator will attempt to find transformations through an intermediate Coordinate system. An administrator can change this setting if desired.
  • Disable Manual Transformations - By Point Database Conversion jobs and Vector Data Conversion jobs allow the user to specify a manual transformation, instead of choosing a standard coordinate system conversion. An administrator can change this setting if desired.

Batch Transformation
We've been told by many of our customers that Geographic Calculator's processing speed and easy-to-use batch routines have saved many production hours, which is welcome news to any project manager. Try out the software for yourself and see how much time it will save you.

Seismic Survey Conversion Tool
Access, maintain, and convert your SEG, SPS and UKOOA formatted ASCII files natively, who knew software could do that?

Now load and convert SEG Y files natively (Society of Exploration Geophysicists open standard) and save these projects for your colleagues to use.

Layer Splitting
Convert only the layers you need to in your multi-layered vector file.

One of the fastest Windows applications for LiDAR processing around.

Display and reproject your DEMs into the right coordinate systems.

Best Fit
Create a fitted coordinate system definition to align your locally referenced data to a known coordinate reference system.

Horizontal Time Dependent Positioning
For certain transformations, we now support the 4th dimension (date selection) as you can select the epoch relevant to your coordinate transformation.

Assign a relationship between your data and its location on the Earth by georeferencing points in your data to known control points on the ground, but beware to 'Mind the Gap Between World and Map'.

Data Corral
Forgot where you saved your data? The Data Corral tool keeps all of the recently used data in one place, you can even save it into your project for future reference.
