[gdal-dev] gdaladdo problems with compression

2015-09-14 Thread Stefan Ziegler
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
