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.

The license models described here require only a unique payment. No additional payments are raised as a function of the number of customer installations or on the service life of the license. The unlock code provides you with the right of using the geodetic functions. Several licensing models are available:
Single license: Geodetic functions can be called from a single commercial software application including the application updates and distributed to any number of clients or can be used in a single Internet application.
General license: Geodetic functions can be used in any number of commercial software applications including application updates and distributed to any number of clients and they can be used in an unlimited number of Internet applications.
Internal License: It entitles the licensee to use the geodetic functions with any number of applications developed by the licensee. Applications developed by the licensee using the Geodetic Function may not be distributed to customers and may not be installed on an Internet server. Applications created with this license must be in context with tasks of development, research and education.
