Hello all - 

I'm having trouble converting a one degree DEM into GRASS
format.  I ftp'ed two DEM's from 'resdgs1.er.usgs.gov',
created a new LOCATION in lat/long.  But when I use
m.dem.examine or m.dem.extract I get a zero coordinate
for one edge.  GRASS also insists on reading it as UTM
based.

file #1
SAN FRANCISCO - W

min elevation: 0.000000  max elevation: 130.000000

ns_res: 0.000000  ew_res: 0.000000
# of columns in file = 0

file north UTM = 136800.000000
file south UTM = 133200.000000
file east UTM = 0.000000
file west UTM = -446400.000000

So the values are all messed up.  Any ideas what I am
doing wrong??
