So, this house has the official address "Groenestraat 42, Staden", but the driveway opens on "Groenestraat, Roeselare"? And the problem is that if you add it to the associatedStreet, the house will look like it's in Roeselare, right? That is tricky, but the problem is not the relation linking the street and the house, but that the relation is tagged as being in Roeselare.

'Closest street' is 100% accurate, but the street a house belongs to is not necessarily the closest one, especially if you were to consider a street that crosses a town boundary to be two separate streets. To take a similar problem, if you have a house that is divided in half by a postcode boundary, how do you determine in which postcode the house belongs? This is the kind of problem I had in mind when I said, in my first mail, that such a search was "not necessarily accurate". I do see your point that you shouldn't tag what you can find in a 100% accurate search. Of course, that leads me to the question of "Why do we add addr:city at all, assuming that every house is fully within a city's boundaries?" _______________________________________________ Talk-be mailing list Talk-be@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-be
