If you use a relation shouldn't it be a site relation instead of a multipolygon?

Re: [OSM-talk] Tagging POI's - Nodes vs. areas
Mark, You're correct- there's no set standard here. OSM uses folksonomies which overlap and change over time. Specifically the question of tagging amenties or shops as buildings or nodes is one where we as a community don't have complete consensus. The general feeling in the US from my experience is that if a building is only used for one thing, then tag it as such. Your example of a hospital is exactly right- and so are many schools. But then you have places where buildings are multi-use. I live in Manhattan and single use buildings are the exception rather than the norm here, so amenities or shops are usually tagged as nodes within the bounds of the building. You're right that even here, hospitals are exceptions- so are many (but not all) schools, and many (but not all) places of worship. To add to the confusion, you didn't even bring up the issue of relations. What if a hospital consists of multiple buildings? That would be a good candidate for a multipolygon relation, in which case you'd add the tags like name to the relation. Getting back to your question- this is a matter of opinion but here's what I'd do if I was you: If the building is a hospital, tag it as such. If the hospital has only one building, the name of the hospital is the name of the building. If the hospital is a subsection of a larger building (floors 1-3) then tag it as a node. If the hospital is multi-building, then I'd tag each building as building=hospital, set the name to whatever the building names are (Building 1, or Heart and Lung Center), then make a multipolygon relation consisting of each of the hospital facility, and set the hospital name there. - Serge ___ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk

Re: [OSM-talk] Tagging POI's - Nodes vs. areas
`amenity=hospital` is what makes it a proper hospital. You can create a node where the hospital is, or an area around the property of the hospital. Drawing either a node or an area is ok, but drawing areas is preferred if you have time for it. If the hospital is just one building, you can add `building=yes` or `building=hospital` to the amenity. If the hospital is a campus of several buildings, you can draw each building as well. `building=*` (anything) should make it render like a building/structure.

Re: [OSM-talk] Tagging POI's - Nodes vs. areas
Hey While this email would rather suit tagging@ or help.openstreetmap.org I gonna try to answer: First of all, please, do not mix building-use and building=*. The later is for the construction type which might overlap with the actual use. amenity=hospital is the tag for a hospital and needed to get it rendered but this can include several buildings and even the surrounding area. Well, for a single building both might be needed: amenity=hospital building=hospital/yes name=* cu colliar Am 21.04.2015 um 15:58 schrieb EthnicFood IsGreat: I want to know how to tag buildings which are also amenities or shops.

That's just one of OSM's nightmarish disasters. +1, basically you would tag buildings with the building tag, and either the building type or yes as value, while functions are tagged with different tags. building=hospital doesn't say there is an active hospital, it only states there is a hospital building. On the other hand, functions like schools or hospitals typically extend beyond a single building (eg there might be a yard, a garden/lawn, a parking etc), so the normal situation would be to map an area for this function and within the buildings with their building types (or yes). If you encounter a building that is (entirely or at least for one entire floor) occupied by something that doesn't extend beyond the building area it might still be better not to mix these 2 entities on the same object (but I admit it is frequently done). If you want to distinguish between these two you can for example map the building as area and create a multipolygon relation with just one outer member (the building) for the function. Alternatively you would have to create an overlapping way which is less elegant and harder to edit, or you just use a node inside, what will loose information (about the extent).
