GeoDLL - Geodetic Development Kit
Function group "Transformation Parameter"
GeoDLL - Calculation of Helmert and Molodensky parameter sets
GeoDLL supports the development of geodetic software by providing geodetic functions, which are put together into function groups for specific tasks.
To calculate Helmert and Molodensky parameter sets in own developments a license for the function group "Transformation Parameter" can be purchased.
This function group provides functions for the calculation of highly exact transformation parameters for the Spatial Helmert and Molodensky Transformation, which make possible precise Coordinate Transformations from one Reference System into another.
The determined transformation parameters can be entered directly into suitable transformation software, e.g. TRANSDATpro Coordinate Transformations, or into the calculation software of GPS receivers to do exact Coordinate Transformations.
The seven respectively three exact transformation parameters are computed with the aid of up to one million identical points.
Those are points with known coordinates in two different Reference Systems.
Identical measuring points of higher order can be inquired or referred by the official measurement surveys.
The coordinates of the identical points can be tested on outliers and residuals by different statistic functions.
The quality of the computed parameters can be documented by a residual matrix and by the computation of the middle, maximum and root mean square (RMS) deviations.
The seven parameters of the Spatial Helmert Transformation are calculated in the three standards "Coordinate Frame Rotation", "Position Vector Transformation" and "European Standard ISO 19111".
The three parameters for Molodenky parameter sets are calculated using the "Standard Molodensky Transformation".
Characteristics of the group "Transformation Parameter"
- Calculation of Seven Helmert Parameters from identical points
- Calculation of Three Molodensky Parameters from identical points
- Calculation of outliers in a group of identical points
- Calculation of the residuals from a group of identical points
- Calculation of the "Maximum Spatial Residual" from a group of residuals
- Calculation of the "Average Spatial Residual" from a group of residuals
- Calculation of the "Root Mean Square Residual" (RMS) from residuals
Functions of the group "Transformation Parameter"

The programs TRANSDAT, SEVENPAR, NTv2Creator, 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.
