I think your problem is more related to GDAL than to QGIS. You should join the GDAL mailing list. May be this discussion will help you : <http://osgeo-org.1803224.n2.nabble.com/Michigan-GeoRef-Michigan-Oblique-Mercator-EPSG-3078-td6517423.html> Jean-Claude _______________________________________________ Qgis-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/qgis-user
