Order SEVENPARSEVENPAR is a tool for the calculation of highly exact seven transformation parameters by the Spatial Helmert 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 transformation parameters are computed with a set of individual identical points. Those are points with known coordinates in both reference systems (geodetic datum). Cartesian coordinates or geographical coordinates with or wihtout ellipsoidal height using the ellipsoid dimensions are suitable. Identical measuring points of higher order can be usually inquired or referred by the official institutions for measurement. The necessary ellipsoid half-axis 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 seven parameters of the Spatial Helmert Transformation 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 most usual standards. Those are the Coordinate Frame Rotation, the Position Vector Transformation and the European Standard ISO 19111.
The program has a user-selectable German or English interface and comes with extensive bi-language online help. It can be run on most common networks and it is possible to use Terminal Services on WINDOWS Servers. The client installations are done automatically.

Administrative Reform in Saxonia
The administrative data bases of the Federal Republic of Germany "Geo Data German Admin" were updated to the reference date of August 1st, 2008!
Thus the changes due to the administrative reform in Saxonia are included in all data bases.

Nature Area Classification
The product "GeoData German Admin" has been enhanced with two new data tables containing the "Nature Area Classification" and the Landscapes.
This will allow associating nature area and landscape information to all localities.

GeoDLL supports 3D coordinate- transformations
After our Dynamic Link Library has become super fast by recoding to C++, GeoDLL now is able to calculate 3D coordinate transformations considering the ellipsoidical heights.
As well calculations with cartesian coordinates are possible now.
