I just figured that out after reading the gdalprovider source from QGIS: https://github.com/qgis/QGIS/blob/master/src/providers/gdal/qgsgdalprovider.cpp#L2472 My mistake was that I understood the transformation matrix to default to 0 1 0 0 0 1 When it actually is 0 1 0 0 0 -1 I overlooked the -1 in the GeoTranform docs :D Thanks for your fast response!
