Supported Coordinate systems and Reference systems (datum shifts)

TRANSDAT Geosoftware executes coordinate transformations and geodetic datum shifts between many coordinate and reference systems of Germany, Europe, America, Australasia and world-wide, at high precision and high speed:

1. The current and many historical coordinate and reference systems of all countries of the European Union (EU) including the eastern extensions from 2004 and 2007 and the systems of the European non-EU countries.
2. The US and Canadian State Plane Coordinate Systems (SPCS) on NAD27 and NAD83 and other coordinate and reference systems of the North American continent.
3. The coordinate and reference systems of the Australasian continent.
4. Many coordinate and reference systems of the countries of other continents.
5. World-wide NTv2 grid file supported coordinate transformations.
6. All world-wide coordinate and reference systems in current use.
7. The German coordinate and reference systems of the old and new federal states, the 40 Prussian Soldner Land Registers, the German 'Lagestatus', and exact reference systems of the German federal states.

Here you find a  list of all states and systems supported by TRANSDAT.

User defined coordinate systems

Additional to in TRANSDAT predefined coordinate and reference systems listed under the link above, user defined coordinate systems can be used by the input of the necessary transformation parameters.

User defined reference systems (datum shifts)

During coordinate system selection, the appropriate reference system can be selected automatically or independent from the coordinate system. The reference systems listed under the link above can be used for geodetic datum shift in both source and target coordinate systems. It is also possible to setup user-defined reference systems for transformations into regional grids or custom coordinate systems. The transformation parameters include three translation vectors, three rotation angles and a scale factor in case of the Helmert transformation "Coordinate Frame Rotation" or "Position Vector Transformation" datum shift, or three translation vectors in case of Molodenski three parameters datum shift.

User defined earth ellipsoids

User defined coordinate systems and user defined reference systems require the definition of suitable earth ellipsoids. The definition effected via the selection of pre defined ellipsoids or via the input of the semi axes of the source and target ellipsoids.

NTv2 support

Exact datum shifts in local systems are possible by supporting the  NTv2 standard with grid files.

Direct mode calculations

The source coordinates can be entered directly into the input fields of the program window and transformed using the previously selected settings. The calculated results will be displayed. The program will automatically save the entered source coordinates and the calculated target coordinates to a log file. You can review and retrieve log file contents using external programs.

File based calculations

It is very important to be able to perform fast calculations on large amounts of coordinate data stored in files of different file formats. TRANSDAT allows loading data from Text, dBase, ArcShape and ArcGenerate input files. A large number of Setup options allow the adjusting to different input file data structures. Calculated coordinates can be stored in Text, dBase, ArcShape and ArcGenerate output files. Here again TRANSDAT offers a large number of program Setup options for the output file structure. The program can locate coordinates in text files and replace the located coordinates with the transformed coordinates.

GIS-Systems

Shape files of the GIS systems ArcView and ARC/INFO can be converted directly into an other coordinate system while maintaining the internal data structure. During the file handling the unrestricted conversion between the data formats text, dBbase, ArcShape and ArcGenerate with or without coordinate transformation is possible. In ArcShape files available geometries can be represented in the program internal Shape Viewer.

Multilanguage support

TRANSDAT user interface can be switched between German and English language. Also the electronic documentation is available in two languages.

Network ability

TRANSDAT can be run on most common networks. The client installations works automatically. It is possible to use Terminal Services on WINDOWS Servers like e.g. "Citrix Terminal Server".

Batch processing

The program offers the possibility of working on one or more files automatically from a batch. Thus makes the program TRANSDAT controllable from other programs.

GPS interface

TRANSDAT has an integrated GPS interface to receive coordinates, speeds and motion directions with an inexpensive GPS antenna connected to a serial or USB interface. In a graphical window up to 2500 GPS positions are shown.

Using with own programs

All TRANSDAT geodetic functions are contained in a Windows 32-bit dynamic link library named  GeoDLL. You can make calls to GeoDLL from your programs. Using GeoDLL to perform geodetic calculations in your applications will save you time and expense necessary for development of geodetic transformation routines.

Hardware and operating system requirements

TRANSDAT is a quite complex application. To ensure stable performance it should be installed on a personal computer with the processor class 80486 or higher and at least 32 MB RAM available. The program will run under Microsoft WINDOWS 95 / 98 / 2000 / XP / NT and compatible operating systems.

Basic and Professional version

The characteristics specified here describe the professional expenditure of the program TRANSDAT. A economical basic expenditure, in which most coordinate transformations can be accomplished, excludes only for the specialists reserved definitions of own coordinate systems, reference systems and earth ellipsoids, the batch processing and the GPS interface.
