Hi all,
maybe you can help me with an open problem. I am not sure sure if this is a case of "garbage-in -> garbage-out" or not.
I see a lot of houses with plausible tags addr:housenumber and addr:street which are close to a road that has no name or a different name.
A typical example is a village like Stühren: http://www.openstreetmap.org/node/378300184#map=17/52.89235/8.71508
Almost all buildings are all tagged with addr:street="Stühren", but the main road through the village is the L340: http://www.openstreetmap.org/way/26701165 which has no name and many buildings are close to it.
I'm pretty sure that this is a bug in the OSM data. According to several source the L340 in Stuehren is called "Stuehren", too. I had that already in my old hometown: at some point in the past somebody did remove the street names from all streets, which are B* or L*.
I think the postal address for these buildings is really something like "Stühren 28, 27211 Bassum,Germany"
Yes, that's correct.
With trunk and r3477 in the housenumber2 branch I see rather bad results for this because the housenumbers are only added to those roads that have the name "Stühren". I wonder if the housenumber option should add the name "Stühren" to (a part of) L340 ?
Adding the name to a part of L340 would be the right thing. But this should be done in the OSM data, not by mkgmap. My problem with the automatic mkgmap approach is: there are enough cases, where you cannot reach from such a road the building.
