[GRASSLIST:6152] DEM imports to Grass

[John Doucette]

I am unsure how to import DEM's into Grass.

I have been trying to use DEM's from Data Depot for US topomap areas.  I am
trying to use r.in.gdal which (in man pages) says it can import USGS ascii
DEM's or SDTS format. When I try either of these it get an "Unrecognized
format" error.  What the heck?

I know that I have somehow gotten a DEM into Grass in the past but don't
remember how.

Can anyone give me a clue?

thanks to whoever
