Hi<div><br></div><div>Following this topic I have tested this methodology by converting from UTM 29N to a specific local coordinate system (EPSG:3763) (available at PROJ4)</div><div>gdalwarp -t_srs "EPSG:3763" band_landsat.TIF destination.tif</div>
<div><br></div><div>With that I got a segmentation error, one <span class="Apple-style-span" style="font-family: monospace; white-space: pre-wrap; ">TIFFReadDirectory<span class="Apple-style-span" style="font-family: arial; white-space: normal; "> a lot of <span class="Apple-style-span" style="font-family: monospace; white-space: pre-wrap; ">TIFFWriteEncodedStrip and the destination.tif has a different size.</span></span></span></div>

Greetings<br>
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?<br>
</blockquote></div>
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.<br>

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