Hi all,
I'm wondering if anyone out there has had experience creating
attractive color shaded relief images from DEMs. The basic procedure I
have used is as follows:
1) r.shaded.relief DEM azimuth=270 altitude=30
2) d.his h_map=DEM_shadei_map=DEM
This is the procedure suggested in Markus' book. My problem is that
I always end up with rather muddy-looking results. I have tried all
kinds of variations on this procedure, including different altitude
settings, recoloring the hillshade with a contrast-enhancing
greyscale color scheme before running r.his, etc. No real
improvement. As an example of what I'm shooting for, have a look at
this:

Can anyone suggest a technique for achieving this quality?
