The Main Page contains three independent calculator boxes. If you have the coordinates to transform e.g. in Stereo-70, select the box "from Stereo-70", write your Stereo-70 coordinates to the Input cells, an the resulting Gauss-Krger and UTM coordinates will appear below. Besides the grid coordinates, geodetic coordinates on the appropriate datum appear. Do not edit them. When you use one selected box, coordinates in the other two boxes won't change. The software uses the direct and reverse equations of the Stereographic, Gauss-Krger and UTM proje (find them in the hidden worksheets). Although the Bursa-Wolf equations are used in the datum shift tra parameters are still unknown. Stereo-70 and Gauss-Krger are interpreted on S-42 (Pulkovo) datum, old Stereo coords are on the Kesztejhegy 1890 datum and UTM coordinates on WGS84 datum. No othe Concerning the Gauss-Krger and UTM, the meridians of 0, 6, 12, 18, etc. degrees are real discriminati lines: zone numbers are depending directly on longitudes. E.g. you cannot calculate the UTM Zone 33 coordinates of a point situated east of 18 degree in this version. The Bursa-Wolf datum shift parameters can be set in Parameters page. Edit them with caution. The grid equations are accurate to millimeter-order. The Bursa-Wolf method provides not so good accuracy: thorough all Romania the error can reach ten meters.
