Description

Reported on mailing list : """ I've also been toying with the compression settings lately and thought I would mention my experience. I'm not sure if this is known behavior, but when subsequently using the compressed rasters with 'gdaldem' I got some strange results when the raster was greater than 4GB (i.e. BIGTIFF). The resulting rasters were either corrupt, way way larger than they should have been, or I terminated before they completed due to the extreme length of time (> 2 hours) they took to process. When I used an uncompressed BIGTIFF raster with gdaldem, the results were as expected. This was all using gdal 11.0, and the following BIGTIFF compression settings, -co "TILED=YES" -co "BIGTIFF=YES" -co "COMPRESS=DEFLATE". """
