Hello I'm trying to built a cost surface. I've already built a raster with the pixel cost, but i can´t get the cost that is required to arrive to point A. I'm trying - "r.cost input=r_v...@12_03 output=exp start_rast=h_r...@12_03max_cost=0 percent_memory=100" but it takes a lot of time and the result it's linear, it do not reflect the differences in the original raster.
I' trying to do something similar to the cost weighted function in arcgis. Tks
