GeoDLL - Accurate Coordinate Transformations

GeoDLL supports the development of geodetic software by providing geodetic functions, which are put together into function groups for specific tasks. To use accurate coordinate transformations in own developments a license for the function group "Coordinate Transformations" can be purchased.

GeoDLL performs Coordinate Transformations fast and with high accuracy. For this purpose the DLL supports thousands of worldwide Coordinate Systems, geodetic Reference Systems, Reference System Transitions (geodetic datum shifts) and Meridian Strip Transitions, user-defined systems, 2D/3D transformations, INSPIRE, NTv2, HARN, BeTA2007, EPSG, GPS, Continental Drift and more.

Characteristics of the group "Coordinate Transformations"

  1. Coordinate Transformation
  2. Reference System Transition
  3. Meridian Strip Transition
  4. 2D and 3D Coordinate Transformation
  5. Helmert and Molodensky Reference System Transition
  6. NTv2 and HARN grid file support
  7. Forward and backward transformations
  8. Numeric and alphanumeric coordinates
  9. Geographic and Cartesian coordinates
  10. Many projections (also rarely used ones)
  11. Thousands of predefined systems
  12. Use of EPSG codes
  13. Use of Measurement Units

  8. Function coordtrans3d3() - 3D Coordinate Transformation / Datum shift, only numeric
  9. Function coordtrans3d4() - 3D Coordinate Transformation / Datum shift, only numeric, no notations
  10. Function coordtrans3dex() - 3D Coordinate transform. / Datum shift, reduced eastings
  11. Function coordtransepsg() - EPSG code Coordinate Transformation / Datum shift
  12. Function meritrans() - Meridian strip change with GK und UTM coordinates
  13. Function setcoordarea() - Coordinate System range check on / off

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 for himself and our customers.
