New tools for the realization of accurate Geodetic Datum Transitions




At many historical places or at fixed measuring points, precisely measured geodetic pass points in two or more Reference Systems are available. If an area contains a sufficient number of these coordinates, also known as \”identical points\”, a method for the Datum Transition can be calculated based on them. Thus, exact coordinate transformations between two Reference Systems can be realized for any desired points within the area.

With the new and so far unique geo software NTv2Creator, KilletSoft provides an economical and nevertheless powerful tool for modelling accurate NTv2 grid files from up to one million identical points. The program is designed in such a way that usable grid files according to the NTv2 standard can be generated even without special geodetic knowledge.

Who prefers the traditional way, can produce exact Helmert Seven Parameter Sets from up to one million identical points with the completely renewed program SEVENPAR by KilletSoft. The program supports the standards \”Coordinate Frame Rotation\”, \”Position Vector Transformation\” and \”European Standard ISO 19111\”.

Nearly all GIS and transformation programs support Datum Transitions with NTv2 grid files and with Helmert Parameter Sets. Both methods are suitable for high-precision Coordinate Transformations between two Reference Systems, which are required for example in the context of the INSPIRE implementation. Detailed information about the programs NTv2Creator and SEVENPAR, as well as the possibility to download free trial versions can be found on the KilletSoft web page https://www.killetsoft.de.
