Hi we are facing problems with the compression of the overviews we are adding with gdaladdo. The filesize does not differ whether we are using compression parameters or not. The filesize of the input raster is approx. 100 mb. The following both commands resulting in an identical filesize of approx. 140mb.
gdaladdo -r average 591252_12_5cm.tif 2 4 8 16 32 gdaladdo -r average --config COMPRESS_OVERVIEW JPEG --config PHOTOMETRIC_OVERVIEW YCBCR --config INTERLEAVE_OVERVIEW PIXEL 591252_12_5cm.tif 2 4 8 16 32 The input raster is tiled and compressed with deflate (and predictor=2) I would expect that the latter one would be smaller. Did we misunderstand something? Or do we use the parameters the wrong way? GDAL 1.11.2 and dev. regards Stefan
