I think the actual coordinates in the .MAP file are stored differently depending on the coordinate system specified in the header. They're always 4-byte integers, but the values stored in them are not always representing degrees. But I'd have to check that to be sure. So if is the case, you will always have to convert all coordinates anyway when you change a table's coordinate system. - Bill Thoen --------------------------------------------------------------------- List hosting provided by Directions Magazine | www.directionsmag.com | To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] Message number: 11415
