Here is the result: projection: 0 (x,y) zone: 0 north: 5682231.5 south: 5679169.5 west: 469641.5 east: 472228.5 nsres: 1 ewres: 1 rows: 3062 cols: 2587 cells: 7921394 I must admit that I am quite new in GRASS, and I don't master all the concepts. Is the raster too big? Do I have to increase the memory allocated? In this last case, I don't know at all which module to use. > > > .
