In that case, you have to first test the geometry type ( geometry.GetGeometryType() ) If equal to ogr.wkbPolygon, apply the above method. If equal to ogr.wkbMultiPolygon, iterate over the polygons with geometry.GetGeometryRef(i) the index varying between 0 and geometry.GetGeometryCount() (which in that case will be the number of polygons). For each polygon, apply the above method. > > -Mike > _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
