I'm a beginner at CoordTrans and have had problems with converting Italian coordinates from latitude/longitude in Monte Mario Rome to Easting & Northing values in WGS 84 UTM 32N. It seems that CoordTrans is using Greenwich as the prime meridian, not Monte Mario, so all the longitude to easting conversions are wrong. Support suggested using manage datums and grids. I thought this was a simple, accurate coordinate transform program that would do this for me. Is it not a bug that a reference meridian is incorrect? I don't know the correct parameters to enter for this 'new' grid. Can anyone offer assistance on this?
