Description from the Publisher

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.

The spatial software NTv2Poly replaces the rectangular activity scope contained in NTv2 files with a Polygonal Validity Scope, which is realized with an outline file in classic Shape Format.

NTv2Tools Geosoftware provides a toolbox for developing and processing of NTv2 files in binary and ASCII formats. With the included tools NTv2 files can be analyzed, graphically or textual displayed, converted and areas can be extracted.

Geodata International - World-wide database of countries with georeferenced towns, municipalities, postal codes and administrative units with WGS84 and UTM coordinates and elevations for geocoding, proximity search, navigation, distance calculation.

The freeware program CONVERT from KilletSoft converts databases and files between the dBase, CSV and SDF data formats and the character sets ANSI, ASCII, UTF8 and Unicode. Thus the import of the data in any DBMS will be possible.

TRANSDAT Coordinate Conversion supports thousands of coordinate systems and geodetic datum shifts, user-defined systems, INSPIRE, NTv2, BeTA2007, GPS, continental drift, Shape, KML, CSV and other file systems and much more with highest accuracy.
