GeoDLL - Geodetic Development Kit
Function group "Parameter Determination"

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"
- Determination of GeoDLL codes equivalent to EPSG codes
- Parameter, notation and range validity of Coordinate Systems
- Parameters of Reference Systems and Reference System Transitions
- Semi-axes and flattening of Earth Ellipsoids
- Designation and parameter of Measurement Units
- Formatted text representation of a Coordinate Reference System
- Determination of many other parameters used by GeoDLL

"Geodata Germany" has been updated on the data conditions of January 1st, 2020.
The database contains Towns and Municipalities, Town Districts, Coordinates, Postal Codes, Dialling Codes, Wind and Snow loads, Solar irradiation etc.
Following Baden-Wuerttemberg with its close-meshed NTv2 grid file BWTA2017, the federal state of Bavaria as well has completed extra high-resolution NTv2 files for the transformation of spatial data in real estate cadastres to UTM/ETRS89.

The programs TRANSDAT, SEVENPAR, NTv2Poly and NTv2Tools 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.
Everybody who is interested can translate a new language file into his native language for himself and all users.
