Brief Description of the Current Version
Program Description Screenshots Download SEVENPAR Prices SEVENPAR Order SEVENPARSEVENPAR is a tool for the calculation of highly exact seven transformation parameters for 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 SEVENPAR is equipped with an up-to-date graphic user surface which handling can be understood intuitively. For each window detailed help texts can be shown. The user surface can be switched between German and English language.
The program SEVENPAR can be run on most common networks. The client installations works automatically. It is possible to use Terminal Services on WINDOWS Servers like e.g. "Citrix Terminal Server".

Spatial data updates
The contract between a data distributor and GeoKontor was terminated in June 2008.
With immediate effect, KilletSoft has been commissioned to organize an update service for the spatial data ("geodata") acquired by them in the years 2006 to 2008 at the level of Zip code (post code), streets and individual buildings.
Please contact us if you require an update of such data.
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.
