Hi all,
some month ago we discussed the idea to implement addr:place support. It it assumed that an address has addr:housenumber and either addr:place or addr:street. Up to now those with addr:place are ignored. It is also assumed that the addr:place tag is used in hamlets and small villages and that the roads in such a hamlet have no name.
I've coded the following simple approach: For each element (node/way) with addr:housenumber=* and addr:place=* and addr:street!=* search the nearest routable way that has no name (mkgmap:street!=*) If the closest road is within a given range (150m), store the place name as a possible road name. Perform a 2nd search to find also the closest road with a name or ref. If we find exactly one possible name for the road, use it.
As a small example - I have a small Hamlet here called Bosfeld beloning to a town called Rheda-Wiedenbrück with a suburb of Rheda. The main street through Bosfeld is called "Bosfelder Weg" although all adresses are "Bosfeld 1" through 60 or something. So mkgmap:street!=* will be wrong in finding the next routable way.
