Hi list, I want to calculate a cost of getting from any cell in my raster to some ports, considering roads network, and I though r.cost could solve this.
What I have is: 1) Cost raster map with cost per cell (10 for normal cells, 1 if it's a road) 2) vector map containing several ports 3) start_raster has the same extent of the cost raster, but all cells == 1 This is the command I'm using r.cost input=cost_map output=cum_cost stop_points=ports start_raster=my_region However, my results is a map will all values equal zero. Is it because the stop_points in ports lay inside my start_raster? Thus r.cost reaches the stop point right from the start? My final result should be a map of distance to ports considering the roads network. Cheers Daniel
