I tried the following in QGIS with the Grass Plugin:
r.cost input=preCostSurface@albi start_points=OSMroads@albi output=cost0109 max_cost=0
And I get the following error:
Dev note: Adapted sites library used for vector points. (module should be updated to GRASS 6 vector library) ￼No start points Finished with error
What is causing that and how can I fix it?
Edit: It seams like this is a general Grass 6.4.3 issue and will be resolved in Grass 7. Does anybody know a workaround for that problem meanwhile?
