as long as you keep the current way for navigation, and just add area:highway there is no problem. Just follow the area:highway instructions on the wiki and the navigation will not get broken. I experimented with in on a small area and navigation still works. I contacted 2 mappers that map landuse in great detail (one in Germany/Italy, one in Japan) and asked them for some samples. I doubt that multipolygons are the way forward, too complex to maintain I fear. We should look at detailed areas in e.g. Germany and see how they do it. m _______________________________________________ Talk-be mailing list Talk-be@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-be
