Hi list,
A while ago I asked a similar question about calculating cost to port
considering a road network. I got this sorted out and results look nice.
But now I'd like to include some rail lines in the analysis.
The problem is that if I just add rail lines to my cell cost raster, the
rail lines
Wow, that was fast. I was just about to reply the I found out I should put
the ports as starting points. And that is clearly stated in the manual
https://grass.osgeo.org/grass70/manuals/r.cost.html#shortest-distance-surfaces
Thanks all
Cheers

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)
