That would be helpful. Regarding gdalinfo, - gdalinfo would report what it does right now (includes any STATISTICS_* metadata items) - gdalinfo -stats would compute raster band stats using all grid cells, ignoring any STATISTICS_* metadata items - gdalinfo -approx-stats would compute raster band stats using a sample of all grid cells, ignoring any STATISTICS_* metadata items Markus > > -Jukka Rahkonen- > > > > -- > Sent from: http://osgeo-org.1560.x6.nabble.com/GDAL-Dev-f3742093.html > _______________________________________________ > gdal-dev mailing list > gdal-dev@lists.osgeo.org > https://lists.osgeo.org/mailman/listinfo/gdal-dev
