Simutech - Version HIS-3D -Environmental Data Management Software

Data Sources

• from highly frequent data series of one parameter (quantity) up to singular environment reports of some hundred parameters (quality)
• online measurement, data collectors, digitised data values, files in different formats
• e.g. water stage and flow, chemical, biological values, meteorology, profiles (geodesy), etc.

Measurement Station Information

• stored in the database with timing information
• e.g. station name, coordinates, contact person, as well as public orders, maps, plans

User Access Rights

• in several privilege steps
• saves data before unwanted access
• protects from unintentional data changes

Data Access

• using thegroup system SPT: station, parameter, time
• cycle time: presentation and evaluation
• are independent from the data sampling interval
• easy access to data values
• presentation in dialogue boxes
• exportable to formatted lists

Editing

• numerical and graphical
• data series: move, turning around a point, copying, adding of values by interpolation and regression with stations in the neighbourhood
• protocol of changes (who/when/why)

Import/Export Of Data Values

• freely formatable; manual and automatic import
• is fault tolerant and learnable against wrong spelled words
• MS-Excel and ASCII tables with data values are simply dragged into the application
• automatic testing during import (e.g. plausibility) and export (e.g. cell formatting at values with boundary value violations, drinking water codex)
• XML for logically formatted exports

Graphics

• widely formatable, storable layout
• 2D-pictures (curve), 3D-surface
• colour intensity plots, isolines

Analysing Methods

• independent from samping interval (e.g. only 7⁰⁰ values)
• all results are output to a file, a graphic, or the database
• Script language (C) for criteria and analysis
• statistics (mean, sliding mean, minimum/maximum, variance, median)
• regression (over time and data series), trend, histogram
• arbitrary algebraic combining of data series (movable over time)
• double sum, flow-duration curve
• polygonalisation (data reduction)
• method and plausibility check

The System Environement

• User Desktop
• The client is available for different operating systems, like MS-Windows (drag-and-drop, clipboard, DDE, OLE, context help).
• adaptable to the user`s needs
• Database
• runs on a server or on the same single workstation
• e.g. Oracle or MS-Access

HIS`3D^® is an open system

• expandable by new methods
• extendable by new data sources and parameters
• open to other packages, e.g.: MS-Excel, MS-Word, ArcInfo, ArcView
• operating system (MS-Windows NT/2000, Linux, Unix) and database independent
