Hello list,
I have a raster obtained through r.mapcalc whose cells values represent
friction or cost.
I suppose that is friction per cell.
To finish my study I'm lacking one final step - calculate the least cost
path!
How do I do it? I've tried r.cost but the result is not wat I expected -
My desired output is just a line from A to B, crossing the least valued
cells.
Use r.cost with the coordinate of (or the vector or raster file
containing) A as start point. Then r.drain with B as starting point.
