I guess that after exceeding some 2 GB or 4 GB limit the pyramids are actually in that big spill file and .aux behaves as an index. Your data are 1 bit and probably very effectively compressed with CCITTFAX4. It may be that Erdas style overviews do not compress very well and I would have a try what happens with TIFF overviews created with something like gdaladdo -ro -r average --config COMPRESS_OVERVIEW CCITTFAX4 test.tif 2 4 8 16 32 64 128 256 -Jukka Rahkonen- _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
