i'm not getting a strong sense of an architecture for getting this data into Nominatim in a useful way, just a bundle of opinions about specific details.
it's not really leading anywhere, in part due to the fact that noone from Nominatim has spoken up. i did just review the Nominatim stuff i found in the wiki. they want postal code polygons in the database; in the US this is the extremely iffy zip code boundary stuff that probably shouldn't go in. i think there are some architectural issues to be resolved, but this is a pretty awful forum for that sort of thing especially given the absence of the Nominatim folks themselves from the discussion. but i did find a workaround. i added is_in=Averill Park, NY, US to Biittig Road and the Nominatim lookup now does what would normally be expected. in fact, for one of the homesites i've tagged with proper address data: 214 Biittig Road, Averill Park, NY US goes to the right spot, which it wasn't before (Nominatim ignores a bunch of the karlsruhe schema tagging on buildings for performance reasons; see the wiki. i had previously entered complete data on the building, but it was never going to find it based on that data alone). it still displays Sliters, Saratoga. even if i fix the Rensselaer County Boundary, it'll just display 214, Biittig Road, Sliters, Rensselaer, 12018 so roundtripping using expected addresses isn't really there. what i still don't get is how it figures out the correct zip code of 12018 for the displayed result string, i guess there's some research to be done yet. how does this differ from zip code boundaries? it does so in several regards: 1) it's more painful to enter, as instead of importing polygons we would need to identify and mark roads with what post office city/town/whatever address is involved (and break ways where boundaries are crossed). 2) it's a little easier in that some postal city designations in the US (mostly for larger towns/cities) encompass many zip codes, and we wouldn't have to deal with that (this is, i think, where the boundaries are iffy in any case.) you end up not worrying about the multitude of zip codes that Albany, NY involves, for example. richard _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
