Thanks Jerry, I've found the trouble with using areas is that sometimes the related buildings aren't within an easily definable area and may be spread across a few different streets with other buildings between them.
This seems very common with large teaching hospitals or university buildings. That's why I was tending towards a relation - and because that's what the wiki said obviously :) Thanks for the tip on multipolygon, I hadn't considered that.

(This may stem from what I found to work when I started out). In the relation I don't think you need the building=yes, but you probably do need something like type=multipolygon.

I traced (from OS StreetView) the seven buildings of the Queen Elizabeth Hospital in Gateshead: [1]http://www.openstreetmap.org/?lat=54.93834&lon=-1.57941&zoom=1 7&layers=B000FTF I've tagged each building as building=yes and placed them in the relation. Then I tagged the relation as amenity=hospital+building=yes+name=Queen Elizabeth Hospital But now Mapnik and Osmarender don't display a name or the hospital POI icon, which rather defeats the purpose. What is the usual approach to this? The Wiki for amenity=hospital suggests: "If you have a large hospital campus with multiple buildings, consider combining them into a relation instead of tagging each individual building to be a hospital" -- [2]http://wiki.openstreetmap.org/wiki/Tag:amenity%3Dhospital ..which I thought was what I had done. Should I also add a POI node with amenity=hospital somewhere amongst the buildings? That seems a bit redundant. Thanks, GrahamS PS I'm a new OSMer, so apologies if this is really obvious. _______________________________________________ Talk-GB mailing list [3][email protected] [4]http://lists.openstreetmap.org/listinfo/talk-gb References 1. http://www.openstreetmap.org/?lat=54.93834&lon=-1.57941&zoom=17&layers=B000FTF 2. http://wiki.openstreetmap.org/wiki/Tag:amenity%3Dhospital 3. mailto:[email protected] 4. http://lists.openstreetmap.org/listinfo/talk-gb
