Possible. But I won't start hacking the Map data, also updates would get difficult. But I already uploaded a new version which stores ids and lat/lon in the ways so that osm_server will deliver osm files with correct ids. _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/dev
