i fixed my previous problem...i can see the map on the display (it was because
of the wrong resolution setting: in fact i had to add to the r.proj command the
parameter res=<resolution of the raster converted into the map units of the
I can see my raster map, but the raster changed shape: all the printed squares
of the utm system became rectangles....mmm
i guess it has got smthing to do with the resolution setting...
