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 6.03 - Latest update on 24 March 2016
The latest important changes

  1. WINDOWS©10 certification after 32Bit / 64Bit intensive test.
  2. Calculation with up to 30.000 identical points.
  3. More performance for parameter calculations with C++ functions from GeoDLL.
  4. Calculation of a rotation matrix.
  5. Output of window contents in GIF/BMP files.

Brief description

SEVENPAR is a tool for the calculation of highly exact transformation parameters for the Spatial Helmert and Molodenski 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. TRANSDAT 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 upto 30.000 identical points. Those are points with known coordinates in two different Reference Systems (geodetic datum). Suitable are Cartesian Coordinates and also Geographical Coordinates and UTM Coordinates with ellipsoidal height using the earth ellipsoid dimensions. Identical measuring points of higher order can be inquired or referred by the official measurement survays. The necessary ellipsoid half-axes and flattenings are available in the program for the selection from lists.

The coordinates of the identical points are tested intensively on outliers and deviations by different statistic procedures. The quality of the computed parameters is 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 Molodenski Transformation".

The program has a user-selectable multi language interface and comes with extensive online help. The program can be run on most common networks and it is possible to use Terminal Services on WINDOWS Servers. In case of a network installation the clients are installed automatically by the program.

KilletSoft Logo Translators wanted!
 
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 by himself.
