In this case, I'm looking to tag a gas station that has a central building (a convenience store) and the separate covered area for gas pumps. Should I use a multipolygon relation? If so, what would the roles be if there is no "inner" and "outer" (as in the example of a building with a courtyard) but rather just two separate buildings? asked 06 Jan '14, 14:05  wdpk |

In this example you could tag the whole area of the fuel station with A similar method works for schools. In the more general case I have seen buildings tagged as multiple outers in a multipolygon relation with no inners. answered 06 Jan '14, 14:12  EdLoach ♦ |
Hi what about building=yes with tags for the available merchandise. The covered area for or with gas pumps is just that building=roof or covered=yes. And separatly tags not a polygone. answered 06 Jan '14, 14:12  Hendrikklaas 2 ps read this as well https://help.openstreetmap.org/questions/22083/should-petrol-station-facilities-be-mapped-separately (06 Jan '14, 14:14) Hendrikklaas |
You don't need 'multipolygon' relations. Either you can draw a single polygon (a closed way) and that's it. Or the business is spread in multiple locations and you have to use the relation 'site'
