GeoDLL supports the development of geodetic software on various platforms by providing geodetic functions. GeoDLL contains precise functions of the themes 2D and 3D coordinate transformation, geodetic datum shift and reference system convertion, MERIDIAN strip changing, user defined coordinate and reference systems, distance calculation, Digital Elevation Model, NTv2 handling, Direct / Inverse Solutions and map function. GeoDLL supports all by the INSPIRE directive prescribed ETRS89 conversions with NTv2 Grid data, e,g. Gauss-Kruger / DHDN to UTM / ETRS89 with BeTA2007.
GeoDLL enables to perform professional grade coordinate transformations in own programs:
User coordinate systems, local reference systems and EARTH ellipsoids can be defined, based on the coordinate system parameters, the semi axes of the earth and seven Helmert or three Molodenski datum parameters.
