[GRASS-user] Error exporting to tiff

[Andrea Peri]

I create it from new retrieving the settings from the original geotiff I load.

Actually the region settings are this:

g.region -p
projection: 1 (UTM)
zone:       32
datum:      wgs84
ellipsoid:  wgs84
north:      5058915
south:      4825185
west:       587685
east:       817515
nsres:      30
ewres:      30
rows:       7791
cols:       7661
cells:      59686851

Thx,
