> Hello Mr. Krueger,
>         I read your question on users_list today. I was faced with the same prob
> lem some time back. "m.dem.extract" works only for 1:24000 scale DEMs. For the 1
> degree chunks we get from the ftp site you have to use m.dmaUSGSread command. th
> e procedure is to read the DEM in using the fore mentioned program and then rota
> te the product using m.rot90. Then the resulting data can be imported into GRASS
>  by "r.in.ll". Try and read the manual for "m.dmaUSGSread" program. It explains 
> in detail the syntax and also the use of "dd" with this command. Hope this works. All the best!
