NTv2Creator geosoftware provides a powerful tool for modelling accurate NTv2 files from identical points in two different Reference Systems.
SEVENPAR calculaties exact parameter sets for the Spatial Helmert or Molodensky Transformation with seven or three parameters, which are used for accurate geodetic datum shifts between different reference systems for coordinate transformations.
GeoDLL is a Geodetic Development Kit / Geodetic Function Library with worldwide 2D and 3D Coordinate Transformation, Datum Shift, Meridian Convergence and Extra Parameter with highest accuracy. Helmert, NTv2, HARN, INSPIRE, EPSG, DEM and much more.
Program that converts geodetical formats to other formats
AllTrans can be used for world wide professional coordinate transformations between international and national coordinate systems. It is clearly arranged and easy to use.
