Purpose of the program SEVENPAR is to produce a set with seven Helmert transformation parameters valid for an specific area, with which then arbitrary points of the area can be transformed from one coordinate system into another with high accuracy. The seven Helmert parameters are calculated in the three most usual standards. Those are the Coordinate Frame Rotation, the Position Vector Transformation and the European Standard ISO 19111.

In the Dynamic Link Library GeoDLL geodesic functions like coordinate transformation, reference systems, meridian strip changes, user defined coordinate and reference systems, distance calculation, maps functions and more geodesic functions of all EU countries, US and Canadian state plane and other systems are contained to bind them into own WINDOWS applications. The DLL is delivered with interface source codes to many programming languages.

TOPOWIN is a state-wide register of the German topographic cartographies and of localities with geo references in different coordinate systems. It also is a topographic information system. The topographical maps of different standards can be determined by the complaint of known parameters or by the direct selection from overview graphics and from sorted lists.
