Hi Even Thanks for your valuable comments. If I understand you correctly I can either access the overviews in the tiles by hand crafting vrt files for each overview level or sacrifice disk space and generate external overviews using your gdalwarp trick [1].
A comment from Frank [2] back in 2005 confuses me. He mentioned VRTSourcedRasterBand in the context of overviews in the tiles, but I only know of VRTRasterBand [3]. Thank you for any further comments, Craig [1] http://lists.osgeo.org/pipermail/gdal-dev/2009-May/020640.html [2] http://lists.osgeo.org/pipermail/gdal-dev/2005-November/007066.html [3] http://www.gdal.org/gdal_vrttut.html _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
