[GRASS-user] Managing UTM different zones

[Nick Cahill]

Would it work to export your map from UTM into  lat/long, and then reimport it into a different UTM location in the zone you want to work in? I did that with a map of the Mediterranean and Near East, all projected into a UTM zone somewhere in the middle. It looks a bit odd but it works.
