Greetings
Firman, but imagine that I have rasters in UTM for differente zones
(e.g. huge countries like USA, etc). How can I produce an automatic
importing tool that uses gdalwarp to project an image to WGS84 and
import to GRASS?
Using gdalwarp you don't have to specify the source coordinate system,
*if* the originals have the correct projection defined in their headers.
For Landsat images, this is most likely the case, so you should be able
to get away with just setting the -t_srs option of gdalwarp and each
tile will be re-projected to the WGS84 geographic CRS.
Thanks for your help
Best regards,
Jenny

Hi,
As far as I know you must define the source coordinate system.
I think it is pretty straightforward when you are using gdalwarp.
If there are so many images, maybe you can create a shell script
to run the process.
