Hi Manfred, What do you mean exactly ?
In CTS, one performs transformations between two CRS (Coordinate Reference System) A CRS uses a specific datum, ellipsoid, prime meridian, and in case of a projected CRS, projection. With all these informations, it can compute transformations from/to WGS84 (geographic or cartesian). What do you mean by geographic transformation ? How do you define WGS84 to MGI(Austria) transformation in other softwares ? Note that all parameters used by cts are in the epsg file (which is the same as the one used by proj4).
