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_translate over my mosaic, having a virtual raster would imply reading from 1000 files in disk, while having a merged tif file would imply reading from just one (much bigger) file. Which approach would be faster?
