[OSM-ja] Fwd: [OSM-talk] street-less addresses and Nominatim

[Satoshi IIDA]

いいだです。

kim-upsilonさんから "町丁単位での行政区域リレーションの作成例"というタイトルでメールが出ていますが、
ちょうどOSMのTalk MLで、Nominatimに対する要望の募集がありましたので転送します。

要約すると、いまのNominatimではStreet Nameをベースに行なっている検索を、
Placeタグをもとにしても行えるようにする、というエンハンスを予定しているようです。

これを拡張すれば、Admin borderで区切られた範囲内に存在するHouse Numberをもとに検索する
(日本の住所体系にフィットさせる)ことも可能になってくるかとおもいます。

とのことなので、これを機会に要望を出せたらと思っています。
言語はC、、、なのかな。
開発に参加できるかたは、コードを参照されるほうが早いかもしれません。

Hi,

due to popular demand OSM's search engine, Nominatim, has recently
received support for the addr:place[1] tag. This tag can be used to
make addresses searchable by Nominatim that do not belong to
a street. Simply replace the usual addr:street with addr:place
containing the region/place the housenumber belongs to.
For example, this building:
http://www.openstreetmap.org/browse/way/185887900
can now be found with this query:
http://nominatim.openstreetmap.org/search.php?q=4+Pomocnia

For technical reasons, Nominatim requires that the location in your
addr:place tag is mapped as well (and not too far away). Currently,
it will happily attach your address to admin boundaries level 8 and
higher, to place nodes of village level or smaller and also
to named landuses. (The latter might be useful for block-based
addresses.)

This hopefully allows to cover most addressing schemas but there is
one known exception: the conscription number schema used in some
parts of Eastern Europe. Nominatim will either pick up the
conscription number (if you add addr:place) or the street number
(if you add addr:street) but it cannot process both at the same
time. This will be fixed at some point but requires more extensive
changes.

If your country has some other addressing that still doesn't work
with Nominatim, please let us know, preferably via trac[2] or github[3].

Happy address hunting

Sarah
