According to the INSPIRE directive in Germany so far in the Gauss-Krueger / DHDN system available geo references must be converted to the UTM / ETRS89 system for future use. BetaDLL supports the development of geodetic software on various platforms for this transformations by providing geodetic functions. BetaDLL contains precise functions for coordinate transformations with datum shifts using the German NTv2 standard BeTA2007. The Functions can be easy called from own applications.
Coordinate systems supported by BetaDLL: UTM coordinates (northern hemisphere); Gauss-Krueger (3 degrees wide strips); Geographic coordinates (Greenwich) [deg,min,sec]; Geographic coordinates (Greenwich) [deg].
Geodetic Reference systems (datum shifts) supported by BetaDLL: DHDN90 (NTv2 BeTA2007), Rauenberg, Bessel; ETRS89 (NTv2 BeTA2007), geocentric, GRS80; WGS84 (GPS NTv2 BeTA2007), geocentric, WGS84.
BetaDLL comes with extensive documentation and is supplied as a DLL file or as C++ source code. The functions of BetaDLL are suitable for multithreading. The DLL is written in the C++ language. That gives very fast performance, compact code, and high stability in use. WINDOWS operating system allows building of function libraries intended for use by applications, the so-called Dynamic Link Libraries. The application uses functions stored in the DLL by making a DLL call. The language used for developing applications that call functions of the DLL is not important. It could be C++, Delphi, MS-Access, Visual Basic or CA-Visual Objects or other. Therefore BetaDLL is delivered with examples and interface source code for many commonly used programming languages.
