Actually, is a *past* known bug, at least for the GTiff driver From GDAL 2.3.0 news: * make it accept to write SetGeoTransform([0,1,0,0,0,1]) as a ModelTransformationTag, and remove particular cases with the [0,1,0,0,0,1] geotransform (#1683) This fix also fixes (0,1,0,0,0,-1) >>> from osgeo import gdal ds=gdal.GetDriverByName('GTiff').Create('/tmp/test.tif',5,5,1,gdal.GDT_Byte) >>> ds=gdal.GetDriverByName('GTiff').Create('/tmp/test.tif', 5,5,1,gdal.GDT_Byte) >>> ds.GetGeoTransform() (0.0, 1.0, 0.0, 0.0, 0.0, 1.0) >>> ds.SetGeoTransform((0,1,0,0,0,-1)) 0 >>> del ds >>> ds=gdal.OpenEx('/tmp/test.tif',gdal.GA_Update) >>> ds.GetGeoTransform() (0.0, 1.0, 0.0, 0.0, 0.0, -1.0) >>> -- Spatialys - Geospatial professional services http://www.spatialys.com _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/gdal-dev T +44 (0) 1756 799919 www.jbarisk.com<http://www.jbarisk.com> [Visit our website]<http://www.jbarisk.com> [http://www.jbagroup.co.uk/imgstore/JBA-Email-Sig-Icons-LINKEDIN.png] <https://www.linkedin.com/in/jon-morris-a2897b4/> [Follow us on Twitter] <https://twitter.com/jbarisk> Our postal address and registered office is JBA Risk Management Limited, 1 Broughton Park, Old Lane North, Broughton, Skipton, North Yorkshire BD23 3FD.
