Do you see your mismatch? If you do g.region vect=yourvector res=whatever it tries to close as possible to the resolution, but it's not aligned with your raster. Some raster modules will issue some warnings or errors. Moritz gave you a good explanation about region settings, masks etc aorund the end of last year. ----- best regards Helmut -- Sent from: http://osgeo-org.1560.x6.nabble.com/Grass-Users-f3884509.html _______________________________________________ grass-user mailing list [email protected] https://lists.osgeo.org/mailman/listinfo/grass-user
