With ALLTRANS you can perform worldwide transformations between state plane coordinates, UTM-coordinates, geographical coordinates and 3d-cartesian coordinates. Manual input and File-Import/Export (ASCII). If the geodetic datum of Start- and Targetsystem is not identical there is a datum shift possible (3-Parameter-Molodenski or 7-Parameter-Bursa-Wolf). ALLTRANS is available in English/German and there is also an Online-Help available. For all countries there are predefined datum shifts to WGS84. For higher accuracies the user can calculate individual parameters using identical points. These parameters then can be stored to the database of ALLTRANS. There is also an outlier test implemented. With an additional Geoid-Modul the user can calculate orthometric heights from GPS-heights.
