I have been trying to extract DEMs in to a lat-long location. The DEMs I
am working on are 1:250,000 scale produced by the USGS. In UTM I followed the f
ollowing set of commands:
1. "dd if= ...."
2. m.dmaUSGSread
3. m.rot90
4.r.in.ll
The last command would put the DEM in my location in raster format. But
when I tried the same proceedure with lat-long the resulting DEM was totally dis
torted. Well actually it did'nt look like a DEM. Does any one have any suggestio
ns.
Sree.
