[GRASS-user] coordinate translation in grass

GRASS GRASS user

Dear all,

for my dissertation, I’m working with Landsat imagery from Tanzania, south of the equator. I’ve set my region in UTM-coordinates in Grass. The problem is that the imagery I downloaded from the Global Land cover Facility did not take into account the false northing of 10 000 000 for areas under the equator, so my north- and southbounds are negative. When I want to load them into Grass using the correct (and thus positive) coordinates, I only get a blank display. So my question is: is there any way to change this false northing in Grass, or to do a translation of my image?

Kind regards,
Annekatrien

You can set the bounds of a raster map using r.region.
