Mapnik renders inner area with nature_reserve+natural=wood blank

Reported by: rsl Owned by: steve8@…

Component: mapnik Version:
Keywords: Cc:


When tagging an inner area as "leisure=nature_reserve" and "natural=wood", the area is rendered blank by Mapnik. When "natural=wood" is removed, the area is tagged as nature_reserve correctly, but information is lost.

Example where this happens in the current openstreetmap view (14.1.2009):

I am unsure whether the renderer should prefer rendering wood or the NR, if uncapable to mix both. But probably it should not be blank. BTW, osmarender renders the combination correctly.

After thinking about this further: It might be caused because Mapnik interprets the inner area only as "natural=wood" (higher prio than the NR) which would be the same as the outer area. So due to the current multipolygon logic the inner is rendered blank.

If yes, maybe this is another reason to get rid of this logic.

Abovementioned area is rendered correctly by Mapnik now. Assumption: This has been fixed somehow.
