Hi Brad, your additional rule is not a good idea, it adds a polygon feature to unclosed lines. I loaded the relation into JOSM and it complains "Multipolygon outer way shares segment with other ring" so the relation is invalid and mkgmap probably doesn't render it. The problem is between these nodes: https://www.openstreetmap.org/node/8977585639 https://www.openstreetmap.org/node/8977553197 I think this way https://www.openstreetmap.org/way/970139137 should not be a member of the relation.

I have a bunch of natural=water lines in my polygons file for various sizes & other natural=water ways work just fine. Any help appreciated. thx Brad _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk https://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
