Hello

how can I convert aspect map's values to azimuth values?
or is there any way to create aspect map with azimuth values?

I think this should work (but you should double check):

if aspect <= 90, then azimuth = 90 - aspect
else: azimuth = 450 - aspect

i.e.

r.mapcalc "azimuth_aspect = if(aspect <= 90, (90 - aspect), (450 - aspect))"
