Yes this sounds like a need feature. I think it shouldn't be too difficult to
programm. You simply have to add another edit field to the second dialog
which holds the scale. As i already pointed out yesterday, I already tried to
separate everything needed for map-import into the source file
src/import_map.c this should help you find the needed source code for this
change. I'll be really happy to review another path for this part of gpsdrive
and import it into the CVS.
