GeoDLL - Parameter Determination of Coordinate Reference Systems (CRS)

GeoDLL supports the development of geodetic software by providing geodetic functions, which are put together into function groups for specific tasks. To determine the parameters of Coordinate Systems and Reference Systems in own developments a license for the function group "Parameter Determination" can be purchased.

The group "Parameter Determination" contains functions to return values of in GeoDLL predefined and user-defined coordination systems, geodetic Reference Systems and ellipsoids.

Characteristics of the group "Parameter Determination"

  1. Custom coordinate systems for many projections
    1. 16 possible projection types
    2. Orthogonal Output Device Projection (Pixel calculation)
  2. Custom reference systems
    1. Coordinate Frame Rotation (Seven parameters, Helmert)
    2. Position Vector Transformation (Seven parameters, Bursa-Wolf)
    3. European Standard (Seven parameters, ISO 19111)
    4. Molodensky (Three parameters)
  3. Custom earth ellipsoids
    1. Semi major and minor axes
    2. Flattening

Functions of the group "Parameter Determination"

  1. Function getepsg2geodll() - Determine GeoDLL codes equivalent to EPSG code
  2. Function getepsgcrsname() - Determine designation of an EPSG CRS
  3. Function getcoordname() - Coordinate System name
  4. Function getcoordsys() - Formatted Coordinate Systems parameters
  5. Function getcoordform() - 2D Coordinate System's coordinates notation
  6. Function getcoordform3d() - 3D Coordinate System's coordinates notation
  7. Function getcoordaxis() - 2D Coordinate System axes names
  8. Function getcoordaxis3d() - 3D Coordinate System axes names
  9. Function getcoordarea() - Range validity values of a Coordinate System
  10. Function getcoordfixref() - Determining Coordinate System has fixed Reference System
  11. Function getcoordstdrefsys() - Default Reference System of a Coordinate System
  12. Function getcoordstdunitpar() - Default Measurement Unit of a Coordinate System
  13. Funktion getcoordproj() - Projection method number of a Coordinate System
  14. Funktion getcoordstrstatus() - Determining Coordinate System is a strip system
  15. Function getrefname() - Reference System name
  16. Function getrefsys() - Formatted Reference Systems parameters
  17. Function getellname() - Ellipsoid name
  18. Function getellsys() - Formatted ellipsoid parameters
  19. Function getellsource() - Source ellipsoid demi-axes
  20. Function getelltarget() - Target ellipsoid demi-axes
  21. Function getunitname() - Designation of a Measurement Unit
  22. Function getunitpar() - Calculation constant of a Measurement Unit

KilletSoft Logo Translators wanted!
The programs TRANSDAT, SEVENPAR, NTv2Poly and NTv2Tools support language files for the programs interface. Since the language dependent texts are managed in external files, link_in new languages can be added at any time by creating new language files. Everybody who is interested can translate a new language file into his native language for himself and all users.
