You can try a pixel-interleaved tiled BigTIFF indeed. So use -co TILED=YES when creating it. Pixel interleaving is the default . For compression, you can for example try -co COMPRESS=DEFLATE . > > Thanks! > Jose _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
