[GRASS-user] cost surface

[Ricardo Almendra]

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_vias  12_03 output=exp
start_rast=h_rast  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
