I've been successfully using the attached command lines in .bat files to
crop and mosaic a large number of tiles. Frank suggested to use
gdalwarp because my input images are large (approx. 2 GB each) and
gdal_merge loads entire images in memory and I was running into problems.
You have to use gdal_merge first to create the image and them use
gdalwarp to mosaic. In my case the src and dst srs are the
same.<br><br>
I also use gdal_translate because I load the tiles into another program
that wants tiffs as INTERLEAVE=PIXEL.<br><br>
Hope it helps.<br><br>

Hi Reinaldo, I've tried to use gdalwarp to mosaic images a couple of<br>
times but haven't been able to get it to work for me. I'm sure it's<br>
because I'm just not getting the syntax right. Would share a couple
of<br>
example command lines with me so I might spot my error?<br><br>
Thanks :)<br><br>
