Hello grassers,
is there anyone, who has experience with a realistic looking shaded relief?
Do I need a raytracing-tool or is it possible to do it with grass-programms?
I'm working with a relative 'soft' dem, but when I visualize with
d.his(dem/aspect), it looks like a high mountain region.
I'm not sure if this got through to the first time I posted it, so here goes again.
Apologies if it turns up a number of times.
An approach I have used with some success which gives a visually pleasing result
is as follows...
(1) apply r.mfilter to your elevation file, using the following filter matrix;
0 -2 -2
2 0 -2
2 2 0
using a divisor of 1
(2) apply a greyscale to the output file
See how that works for you.
Cheers,
