In a discussion with Ivan Gayton of MSF on this subject and his view on the humanitarian angle isthey prefer the area to be shown rather than the node. They use the area in estimating the number of occupants (for which they have worked out an average table for the areas they require). So

I would like to return to the original question: 1.) I think it is confusing to have building=cowshed allowed on nodes, but building=cabin not allowed. We should unify this. Either _all_ building=* keys can be used on nodes, or _none_. 2.) If we agree on 1.), would we opt to allow nodes or to

All building=* on nodes is fine. As others have pointed out, it is often necessary in HOT aerial mapping when we have low-resolution imagery to work from. Also, for humanitarian purposes there are serious uses for node-only buildings, for estimating the population or the population distribution

I see nothing wrong with building=* on a node, used 772612 times. Typical cases are: - somebody collects house numbers along a road, but has no access to the geometry. Thus she can use plain addr: tags on unbuilt properties, and add building=* where a building is visible. - aerial imagery

I must chime in on this discussion. I disagree with Tobias' view. Some of us are mapping in areas with very low resolution imagery. Yet, if a house is visible, especially in remote regions, I want to be able to map it even if it's not clear enough or large enough to have a shape drawn. I have

Hello. The english wiki page key:building says that this key may not be used on nodes. However, most (but not all) of the english wiki pages for the individual values (like building=apartments) allow the usage on nodes. I’m not sure if it is useful to have a different policy for different values
