The program TRANSDAT and the function libraries GeoDLL and BetaDLL supports NTv2 standard coordinate transformations with high accuracy.
Amongst others the NTv2 grid file BeTA2007 can be used for transformations within Germany with results in sub-meter accuracy.
The grid file is provided by the "Arbeitsgemeinschaft der Vermessungsverwaltungen der Länder der Bundesrepublik Deutschland" (ADV), along with a documentation and a set of test data.
The test data contain 31 spaced points on the territory of the Federal Republic of Germany in different variations with coordinates in both reference systems DHDN90 and ETRS89.
The test data are provided by the ADV for the verification of the computational accuracy of transformation solutions with external software.
The results do not make a statement about the accuracy of the transformation system BeTA2007.
Due to the system with BeTA2007 a nationwide transformation accuracy in sub-meter range can be realized.
For allocated areas even an accuracy in the decimeter and centimeter range can be achieved.
Comparative calculations with the test data of the ADV, done by the engineering office C. Killet Software Ing.-GbR, attest to the software TRANSDAT, GeoDLL and BetaDLL a very good self-consistency.
Here are the results:
The good result is not surprising, since for the calculations strict formulas are used only.
The coordinate transformations are performed according to publications of Maarten Hooijberg (1997 and 2008).
The NTv2 date change is made following publications of D. R. Junkins and S. A. Farley (1995).
The comparative calculations were done with the program TRANSDAT indeed, but they are also valid for the function libraries GeoDLL and BetaDLL.
These are used by the program TRANSDAT for the necessary geodetic calculations.
The libraries allow users to include coordinate transformations with high accuracy in their own programs.

Accuracy check
Our products TRANSDAT, GeoDLL and BetaDLL supports transformations with the NTv2 standard BeTA2007.
The German "Arbeitsgemeinschaft der Vermessungsverwaltungen" (ADV) therefore provides a set of test data.
Comparative calculations with the test data attest an accuracy with an average deviation of only 0.02 millimeters.

TRANSDAT language files
The latest version 13.32 supports language files for the programs interface.
Since the language dependent texts are managed in external files, new languages can be added at any time by creating new language files.
Every user of the program can compile language files by himself.
Geo Data German Admin
The administrative data bases of the Federal Republic of Germany "GeoData German Admin" were updated on the data conditions of January 1st, 2010!
The databases contain Towns and Municipalities, Town Quarters, Administrative Units, Postal Codes, Telephone Preselections, Snow and Wind Load Zones, Nature Area Classifications and Landscapes.
Price reduced!
Since February we have a new contract with our data supplier.
The prices for spatial data on street and building levels have been reduced substantially.
The up to 65 percent cheaper prices we pass directly to our customers!
New product BetaDLL
BetaDLL is a programming library with coordinate transformations and NTv2 datum shifts with the German BeTA2007 standard for calling from own applications or the use as C++ source code.
