Does anyone know how I can make a surface roughness map?
the map is made by dividing the area into square inuts, and then calculating
the ratio beetwen the real area and the planar area of each cell.
the basic problem is how to calculate the real area of the surface in each
cell.
tks in advice.

r.surf.area may be contain the basis for such a thing (it triangulates
surface area via adjacent cells). It doesn't produce a raster though...
