It produces a simple polygon without any hole, and ONLY a self-intersecting boundary. This ONLY applies to shapefiles, no problems found with postgis or tab-file writer. Example polygon in WKT that cannot be converted to a valid shapefile: POLYGON ((0 0, 0 3, 3 3, 3 0, 0 0), (0 0, 1 2, 2 1, 0 0)) /Regards Lars " defect closed normal 1.4.2 OGR_SF 1.3.2 normal fixed shapefile llo@… warmerdam Markus Neteler frederic.claudel@…
