I forgot to cc to the list before... so once again, and this time more clear:
* check the projection system information of your tif file with gdalinfo from the commandline. (man gdalinfo for help) * and then... (the message I forgot to cc to the list): You have to know in which coordinate system your "nf42_geo.tif" data is projected. If you are sure that your data is projected in the coordinate system which you assigned in your LOCATION (with g.region -o you get that info as well) then just use an extra option to ignore these errors: -o in the commald line or the respective box in the GUI "Override projection" e.g. CLI: > r.in.gdal -e -o in=nf42_geo.tif out=tm By the way, it is very helpful and saves time and energy to consult tha help pages always. There are (almost) always the necessary examples and explanations.
