Interesting... Thanks for the insights.
And about performance, if I have 1000 JPEG files forming a mosaic, and want
to run gdal tools over that mosaic, which option should I choose?
- Build real merged tif file (gdal_merge)
- Build virtual raster (gdalbuildvrt)
For example, if I want to run gdal

Small correction: gdalbuildvrt can only deal with datasets of the same
projection.

Hello,
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.
At the end, in both cases we have a mosaic from several inp
