Hi Lene, I'm not sure if it is enough to justify such huge output files, but most of the tools in the "raster" menu just output always float64 tiffs, that certainly contribute to make often bigger than the necessary. This has been fixed in Processing where most of the gdal tools now have an option to choose the type of geotiff for the output. cheers -- Giovanni Manghi Faunalia.pt Sistemas de Informação Geográfica Open Source Portugal Web: http://www.faunalia.pt Email & Jabber: [email protected] PGP Key available Tel. + 351 96 7058216 -- _______________________________________________ Qgis-developer mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/qgis-developer
