I am currently working on mapping a city school that has various buildings. The buildings are spread around a few streets and have other unrelated buildings (e.g. houses and shops) and public roads in between them, so I can't just draw an area around the buildings and tag it. I have mapped out the buildings - sometimes using closed ways and sometimes using multipolygons for adjoining buildings - and tagged them as building=school. Some of these buildings have specific names e.g. Old Block, so I have tagged the closed way or multipolygon as, for example, name=Old Block. Currently there is a node positioned at the school's reception to hold the amenity=school, address and website tags. However, this does not show exactly which buildings belong to this school, so I would like to use a multipolygon. (There is also another school nearby, with another set of buildings.) I am using JOSM to edit. Should I create a new multipolygon for the entire school by selecting all the buildings (so that I have child multipolygons)? Or should I select all the outer ways for each set of adjoined buildings and use these to create a multipolygon? Or should I stick with what I have already? If I go for a multipolygon approach, do I need to tag all the buildings with role=outer? Thanks. asked 01 Mar '12, 18:16 Greg |
Check this widely used relation type "site": instead of nesting multipolygons relations. answered 01 Mar '12, 18:36 Pieren This seems to be a good solution. I will edit the wiki page for amenity=school as I wasn't aware that this relation type existed. Thanks.

Use amenity=school like you would a land use, encompassing the entire campus. answered 01 Mar '12, 19:49 Baloo Uriza 2
The campus is spread around so there are a number of other buildings in between which are not part of the campus. I don't really want to map the whole area as a school when it is just part of the city with school buildings in amongst others.

So, it seems like you can manage that landuse of the school by creating a multipolygon for the amenity area, with the donut holes as inner. This would limit areas inside the whole that are not "on campus" as not being part of the school.
