Spatial Helmert Transformation

SEVENPAR calculates from identical points in different geodetic Reference Systems precise parameter sets for the Spatial Helmert, Bursa-Wolf and Molodenski transformation with seven respectively three parameters. The parameter sets can be used by GIS and transformation programs to compute Coordinate Transformations with accurate datum shifts between the Reference Systems.

SEVENPAR - Version 6.05 - Latest update on 1 August 2016
The latest important changes

  1. Printing of the settings and the determined parameters.
  2. WINDOWS©10 certification after 32Bit / 64Bit intensive test.
  3. Calculation with up to 30.000 identical points.
  4. More performance for parameter calculations with C++ functions from GeoDLL.
  5. Calculation of a rotation matrix.

Helmert Seven Parameter Set

In many branches, custom defined areas and situations coordinates have to be transformed into different Coordinate Reference Systems (CRS). SEVENPAR is the tool of choice to calculate a Three or Seven Parameter Set to do coordinate transformations between that CRS. Considering that for both CRS each a list with coordinates of identical points are required. SEVENPAR is an very flexible tool for determining precisely Transformation Parameter Sets. Additional the program calculates a Rotation Matrix, the residuals of all identical points for further use, and as quality criterias the Maximum, Average and Mean Square (RMS) Residuals. The determined transformation parameters can be entered directly into suitable transformation software, e.g.  TRANSDAT Coordinate Transformation, or into the calculation software of GPS receivers to do exact Coordinate Transformations.
