Dear Grass Users,
Is there a simple way of using two map projections simultaneously in GRASS?
I have a GRASS location in UTM, but need to add new maps by digitising
from base maps stored as latitude-longitude. The v.digit command only
seems able to cope with digitising using the same projection as the
original location (in this case UTM). I could resort to using Arc/Info for
digitising, then PROJECT/TRANSFORM into UTM before exporting to GRASS, but
I'd prefer to carry out the whole operation in GRASS if possible.
My suggestion is that you create a GRASS location for lat-long, store your newly
digitized maps there, then convert them to UTM using v.proj (an alpha module in
GRASS).
