Subject: Question about Viewing DLG files in GRASS
Date: 27 Jul 1994 03:57:15 GMT
Organization: Statistics Dept., U. C. BerkeleyI have spent the last two days trying to view DLG files in GRASS
that I installed on a SUN workstation and I am feeling rather
frustrated. I would be very obliged if someone knowledgeable
could tell me what I am doing wrong....

Thanks again in advance.

Shaji,
When you import an optional format dlg file, it is in
UTM coordinates. The header you created is in lat-long.
You need to use the UTM coordinates:
north: 4178342.21
south: 4150401.44
east: 588392.23
west: 566072.83
and you appear to be in UTM zone 10.
The person who suggested using the command: g.region vect=(filename)
is correct, this will set the region to whatever the region is for the
vector file you created...
Hope this helps.
