[GRASS-user] Re: shortest / less steep path in DEM

[Koen Hufkens]

Forgot to post to the list as well,

In short, combine both the length cost map and the steepness (r.slope
output) cost map (according to your preference).

Use this output as input for a final cost calculation.

That should do the trick I think,
