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.
If I've understood your question...
I guess you'll have to divide by the cosin() of the slope,
but why don't you use the stdv or similar within a window?
