I want to have mutiple overview files (one for each overview level) for a GeoTiff, so I’m able to edit this files in a raster editor. How can this be done?
Unfortunately, gdaladdo -ro creates only one .ovr file for a tiff, that contains all the overviews.
Maybe this can be done by using VRT format and specifying particular tiff files as overviews for a main one?
