Hello,<br>
<br>
What's the difference between gdal_merge and gdalbuildvrt? If I'm not
wrong, gdal_merge actually creates a new dataset, merging the input
ones. And gdalbuildvrt just creates a VRT file, which works as
descriptor for a mosaic.<br>
<br>
At the end, in both cases we have a mosaic from several input files
(real mosaic vs virtual mosaic). So, why would I use gdal_merge instead
of gdalbuildvrt? With gdal_merge, I'd need more space in disk, in order
to generate a merged file. <br>
<br>
Many thanks in advance.<br>
<br>
Best regards,<br>
