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.
