The program TRANSDAT and the Geodetic Development Kit GeoDLL support NTv2 standard Coordinate Transformations with high accuracy. Amongst others the NTv2 gridfile BeTA2007 can be used for transformations within Germany with results in sub-meter accuracy. The gridfile 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 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).
