Need help importing DEM data

James,

Looks OK to me, except when you get to the r.in.ll, you have to
use the correct corner for your data. The SW corner for the
las_vegas-e data would be: 36N,115W

r.in.ll input=las_vegas-e.dem output=dem.utm dimension=1201,1201 \
bpc=2 res=3,3 corner=sw,34N,119W spheroid=wgs72

g.region rast=dem.utm

Also, you should ALWAYS do a d.erase after a g.region change!

d.rast dem.utm
