Hi, I have a point in WGS84 UTM32 coordinate E 589747.816 N 4871699.496
I saved in EPSG 3003 with the following coordinates: E 1589776.553 N 4871716.117 A colleague made the same conversion using free software "traspunto" (http://www.mondogis.com/traspunto.html) developed by the Italian Enviromental Ministry. He got this result (EPSG 3003 coordinates): E 1589776.054 N 4871716.382 I try another online tool (http://www.sardegnageoportale.it/webgis/raswebconverter/index?stato_quale=punto) and I found these EPSG3003 coordinates: E 1589776.554 N 4871716.119 Summary: QGIS and sardegnageoportale seem to give the same results, traspunto is different (0.50 meter difference). Which is the correct result? Where can I found the calculation for the conversion from a system to another?
