Yes Sure :)
Attached to this email you can find the log
I was thinking of just the results of gdalinfo. This way we can see if
the tiff is being recognized, and if its CRS is is available in the tiff
header.
Here's an example:

Hi
Following this topic I have tested this methodology by converting
from UTM 29N to a specific local coordinate system (EPSG:3763)
(available at PROJ4)
gdalwarp -t_srs "EPSG:3763" band_landsat.TIF destination.tif
With that I got a segmentation error, one TIFFReadDirectory a lot
of TIFFWriteEncodedStrip
and the destination.tif has a different size.
Can you send the output of: gdalinfo band_landsat.TIF
Any tips of
what migh be wrong?
Thank you
Jenny

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.
