Hi Markus, Here's the output of g.region:
GRASS 6.4.2 (EPSG31467_GK3):~ > g.region -p projection: 99 (Transverse Mercator) zone: 0 datum: potsdam ellipsoid: bessel north: 5867905.9439733 south: 5851898.90994448 west: 3430043.32300553 east: 3440047.55082599 nsres: 0.50020418 ewres: 0.50018638 rows: 32001 cols: 20001 cells: 640052001 Looks alright to me. I set it exactly to the raster in question by using g.region rast=dom_complete. Any ideas? Thanks! :) Daniel -- B.Sc.
