Brief description

GeoDLL supports the development of geodetic software on various platforms by providing geodetic functions. GeoDLL contains precise calculations on the themes 2D and 3D Coordinate Transformation, geodetic datum shift and Reference System Transition, meridian strip changing, user defined Coordinate and Reference Systems, Helmert and Molodenski Parameters, distance calculations, Digital Elevation Model, NTv2 handling and BeTA2007 support, Direct / Inverse solutions, map function, Time Zone calculations and geodetic converting functions.

The operating system WINDOWS provides software developers the opportunity to use prepared functions of third-parties in their own software applications. Thus, geodetic functions of GeoDLL can be linked to programs written in C, C++, C#, Java, Delphi, MS-Access, Visual Basic, CA-Visual Objects or which are written in other programming languages. To support the GeoDLL, examples and interfaces with source code for many commonly used programming languages are provided.

GeoDLL comes with extensive documentation and is supplied as DLL file for 32bit and 64bit architectures or as C++ source code. The DLL works with most programming languages and it can be used with Microsoft Office programs. The DLL is written in C++ and was developed with Microsoft Visual Studio 2010. Thus very fast performance, compact code and high stability are assured. The functions of GeoDLL are prepared for multithreading.

Main Task: Coordinate Transformations

The most important application of GeoDLL is to include professional Coordinate Transformations in own programs. These Coordinate and Reference Systems are supported:

  1. The current and historical Systems of all countries of the European Union (EU)
  2. The coordinate reference systems of the European non-EU countries
  3. The European ETRS89 systems forced by INSPIRE
  4. The US and Canadian NTv2, HARN and SPCS Coordinate Reference Systems
  5. The Coordinate Reference Systems of most countries of all continents
  6. The Coordinate Reference Systems of Austria and Switzerland incl. NTv2
  7. The Coordinate Reference Systems of the old and new German Federal States
  8. The German 'Lagestatus' Coordinate Reference Systems
  9. The special Reference Systems of the German Federal States
  10. The German BeTA2007 and the NTv2 Reference Systems of the Federal States
  11. The 40 Soldner Coordinate Systems of the Prussian Land Registers
  12. The Geographic coordinates in different notations and Cartesian coordinates
  13. World-wide NTv2 gridfile supported Coordinate Transformations
  14. World-wide used numeric and alphanumeric Coordinate Systems
  15. ITRS annual realizations or WGS84 epochs for GPS measurements
  16. WGS84 Coordinate Transformations in consideration of the continental drift
  17. User defined Coordinate Systems, Reference Systems and earth ellipsoids

KilletSoft Logo Translators wanted!
The latest versions of the programs TRANSDAT and SEVENPAR support language files for the programs interface. Since the language dependent texts are managed in external files, new languages can be added at any time by creating new language files. Every user of the program now can compile language files by himself.
