In the idea of replacing r.cost by r.terracost, I would think that the
latter would first have to implement the options in r.cost, e.g.
- equivalents of the start_points and coordinates options of r.cost
- stop_points/coordinates
- max_cost
- the knight's move
- ...
If r.terracost is
This may be because you don't have rights to /var/tmp, or maybe the
directory /var/tmp/mlenert does not exist.
To change this location, you do not need to change main.cc. Instead
use option

Hi Markus, Moritz,
I could reproduce the problem. It was happening because the cost of the
source points were incorrectly assigned to be zero, instead of the
actual cost of the points. Because of this, the immediate neighbors of
the source
Hi Moritz,
Terracost runs in two modes: in memory (when numtiles=1), and in
external memory, using streams (when numtiles1). When run without a
value for numtiles, it sets numtiles to the optimal value. In all
your tests numtiles was set to 1. The algorithms in the 2 cases are
