Julie,
All of the responses that suggest that you edit the appropriate header
file under the $LOCATION/cellhd directory are correct. However, I wanted
to point out to you that if you are working in a projection (UTM, State
Plane, etc.), you cannot readily move in even lat/long increments, as 1
degree will be a different projected distance on different edges of your
raster file. You can readily move 100,000 meters, but not 1 degree. Of
course, if you're Location is set up in lat/long, you can move in degrees
to your heart's content. Just wanted to clarify!
Regards,
