[GRASSLIST:2181] Importing a USGS ASCII DEM

[Ben Logan]

Hi,

I've imported a USGS ASCII DEM using r.in.gdal, but when I use d.rast
to display it, it is all red.  I've tried changing the color table,
but to no avail.  Using d.what.rast show different values at different
places, so I'm not sure why they won't show up in different colors.
This particular dem file has extension ".dem".  I have successfully
imported another USGS ASCII DEM which has extension ".cdo".  Not sure
what the difference is...gdalinfo shows them both to be DEMs.

Here's the data in question:
ftp://gisweb1.radford.edu/dem/county_dem/carroll_dem.zip

Any ideas?

Thanks,
Ben
