How best to map adjacent fenced areas?
Say there are several adjacent properties (residential, retail, school, hospital, whatever), all of which have surrounding fences. I see several ways to map these areas, but do all of them work? And which is best?
1. Map each property as an enclosed area, with adjacent properties sharing nodes. Also tag each area with barrier=fence. This is simple but dependent on the renderer's ability to interpret the way both as an area (for the property) and as a closed way (for the fence). This would also result in overlapping fences, which I'm not sure would be a problem.
2. Also map properties as an enclosed areas sharing nodes, but map the fence as a separate way sharing the areas' boundary nodes. This is less ambiguous, and would allow the fence to be tagged with its own properties, but would result in nodes being shared by at least three ways which may be confusing to editors.
3. Map each shared border separately, tagging it with barrier=fence, and use multipolygon relations to tag the areas using these ways as members. This seems to be the clearest and least redundant method, but also the most complicated, requiring a lot of relations.
