I've tried r.proj as you suggest. The problem is that source location
don't have projection information. Is a XY location. Not georrefenced
location.

I've used this location to fix the extents of a raster map. I get
wrong extents when import some tifs. r.in.gdal reports invalid values
(i.e., lon>180).  But, I've solved this problem by editing the TFW
file manually (I think that this is correct approach).

Thanks Daniel.
