Need help importing DEM data

[James Curry]

Hi,

I'm a new grass user and would like to import some USGS DEM data.
This is what I have done:

downloaded las_vegas-e.gz from edcftp.cr.usgs.gov/pub/data/DEM/250/L

decompressed with gzip

dd if=las_vegas-e ibs=10240 | m.dmaUSGSread top=1 bottom=1201 \
left=1 right=1201 output=las_vegas-e.dat logfile=las_vegas-e.log

m.rot input=las_vegas-e.dat output=las_vegas-e.dem \
rows=1201 cols=1201 bpc=2

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
d.rast dem.utm

All that is displayed is a single very narrow strip.
I'd appreciate some pointers to where I am going wrong. I've tried
get information from moon but can't seem to download any of the archive
material or help docs.

Thanks.
