I successfully cut out of the source DEM a small area matching that of the project watershed. When I ran r.slope.aspect the output maps looked as they should.
Feeling irrationally exuberant that I might be able to quickly move on to hydrological modeling, I just tried running r.shaded.relief on the same raster DEM map used for the slopes, aspects, and curvatures. No joy. the relief map looks like the earlier slope and aspect ones: vertical bands of horizontal static. This is all within the latest weekly checkout of 6.4. What might I be missing if all I specify to r.shaded.relief is the input and output map name and leave the other options at their defaults?
