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 and map function. GeoDLL enables to perform professional grade coordinate transformations in own programs: 1.The current and historical coordinate and reference systems of all countries of the European Union (EU) including the eastern extensions and the systems of non-EU countries. 2. The INSPIRE© supported European ETRS89 systems. 3. The US and Canadian State Plane Coordinate Systems (SPCS) on NAD27 and NAD83 and other coordinate systems of the North American continent. 4. The coordinate and reference systems of the Australasian continent. 5. Many coordinate and reference systems of the countries of other continents. 6. World-wide NTv2 grid file supported coordinate transformations. 7. All world-wide coordinate and reference systems in current use. 8. The German coordinate and reference systems of the old and new federal states, the 40 Prussian Soldner Land Registers, the German �Lagestatus’, and exact reference systems of the German federal states. 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. GeoDLL comes with extensive documentation and is supplied as a DLL file or as C++ or CA-Visual Objects source code. The functions of GeoDLL are suitable for multithreading. The DLL is written in the C++ language. That gives very fast performance, compact code, and high stability in use.

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 functions of the unlocked group. Several licensing models are available:
Single license: Functions of the licensed group 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: Functions of the licensed group 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: Functions of the licensed group can be used only within a single company or enterprise. Distributing to clients and the use in Internet applications under the internal license is not permitted.
