I used r.slope.aspect for curvatures quite a bit and did not have a problem
(except that it does not write the custom color table as the rst programs do
which is annoying)
- I will test it too, but I want to ask whether you had a mask set, because I
might not have used it with a mask.

(If you are computing it to visualize the waves along contours, I am covering
that in the applications, so do not worry about that right now)Neteler wrote:
