Coordinate transformation

Here you can convert single coordinates or whole ASCII files in the area of Germany between the common georeference systems. We offer you a:

        a simple HTTP interface.
        Die HTTP-Schnittstelle erlaubt Ihnen eine direkte Einbindung unseres Coordinate
        Transformation Service (CTS) in eigene Anwendungen.
The coordinate transformation is based on a "Registry" (database) for coordinate reference systems.
Depending on the source and target system the Helmert transformations and a more precise NTv2 transformationen are supported. The Helmert transformation uses a set of 7 parameters, while the NTv2 transformation uses a special displacement grid. The accuracy of the translation corresponds to cartographic requirements in the scale range from 1:25,000 to 1:1,000,000.
Beyond these services, we offer an internationally standardized Web Processing Service (WPS) for the coordinate transformation:

Any liability for the correctness and for damages resulting from the use of these services is excluded by the BKG.
