No, you're wrong. You have to EITHER: - Use the members with "outer"/"inner" roles to build up the multipolygon boundary - Use the members with "subarea" roles to build up the multipolygon area Why is this information duplicated? Don't ask me. If you're really data-quality paranoid, then use both the outer/inner and subarea to build up two models of the country, then see if they overlap or not. P.S.: I had a look at Spain admin boundary and fixed up the roles according to http://wiki.openstreetmap.org/wiki/Relation:boundary - it still has some issues IMHO, but the national-level boundary should be fine. -- Iván Sánchez Ortega <[email protected]> Un ordenador no es una televisión ni un microondas: es una herramienta compleja. _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/listinfo/dev
