For completely unrelated reasons (I was searching for an unfinished railroad and was looking to see if it existed in any property lines) (no, it didn't) (sigh) I had a copy of the parcel data for Oneida County, New York. It has the address in a fixed field, along with the name of the road. It would be trivially easy to set addr:housenumber and addr:street for the parcel. The trouble is that I don't know where in that parcel the building is to be found. And some parcels are quite strangely shaped, e.g. two squares overlapping only at a corner. And then the street name and the TIGER street name vary wildly, e.g. tiger:name_base="State Highway 13" and ocgov:loc_st_nam=Nys Rt 13" (or in another record, "State Route 13 N"). The latter only matters if the property is on a corner. I've noticed that the road is considered to be "unowned", so there's only one way connecting those nodes. Thus, I'll look for the nodes with only one way, and tag the center of those nodes with the address. Might employ some heuristic to guess which road if multiple roads are found. -- Russ Nelson - http://community.cloudmade.com/blog - http://wiki.openstreetmap.org/wiki/User:RussNelson [email protected] - http://openstreetmap.org/user/RussNelson _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
