Yes. And therefore the problem lies in the rendering rules, not the underlying data, that's why these should be modified, not the data. Actually I can think of no case where water should not be rendered above other nearby polygons. The only situations would be covered underground water bodies, which should be tagged with a layer-tag and probably some yet-to-come-underground-tag, so I think this issue can be solved. (Probably the suggestion to map the water explicitly above and tag it with natural water, tidal=yes is the best hack proposed till now, but of course remains unsatisfactory). You lose the fact that the basin itself is part of the park, but I'm not sure how important that is. IMHO it is important. cheers, Martin ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Hillsman, Edward hills...@cutr.usf.edu writes: I have a related question, which I've let sit for several months hoping to find an answer for. There is a park here http://www.openstreetmap.org/?lat=27.8394lon=-82.5924zoom=14layers=B000FTF that includes wetland islands, wetland mainland, and dry mainland. Initially I could not get any of it to render as park. Somehow I eventually dumbed into something that renders the wetland islands as park, but it required deleting the islands and retracing them--not sure why. Anyway, I don't want to have to retrace the mainland wetland coastline to do this, and I also need to connect that with the dry mainland section. The entire wetland mainland area in the view is part of the park, and I know from visits to the area where the northern boundaries for the dry areas are. Can someone advise how to do this? I've stayed away from doing any further work on the local coastline until I figure this out. coastline and park should be entirely separate conceptually. Tag it how it is, and if it doesn't render how you think it should look into the rendering rules. Contorting the tagging to make the current rendering incarnation work right seems like not a good plan. I suspect the rendering folks would be interested in a fix; I can easily see this being a case not envisioned and not handled. pgpl39gQi0EFD.pgp Description: PGP signature ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

It depends on the context. A closed loop tagged with a highway tag is just a closed highway. Roundabouts are often simple closed loops, but render as a ring not an area. There are exceptions of course (it wouldn't be OSM without them :-)) If you want to draw a piazza draw the closed outline with highway=pedestrian which would normally render as a closed loop, but if you add area=yes the whole space is rendered as a filled piazza.
