r.watershed can produce a map of "drainage directions".
The values of a direction map are in the range of -8 - +8
Can someone tell me what these numbers refer to? That is, what
direction is 3 or -3? I've tried to run some correlations against an
aspect map and am not getting meaningful results yet.
Thanks
Michael
