いいだです。 Tagging MLにて、日本におけるadmin_level=3の利用に対する指摘がありました。
詳細は転送の内容を読んでいただきたいのですが、要約すると以下のようなかんじです。 「日本地域で admin_level=3 を付与する編集が行われているが、 admin_level=3は将来の州のために予約されたレベルであり、現在は使わないはずだ。 admin_level=3のタグを削除したい」 私も同意見です。 ざっとoverpassで調べてみたところ、 このタグは、「関東地方」や「中部地方」などの、○○地方のオブジェクトに対してあてられているようです。 http://www.openstreetmap.org/relation/532759 http://www.openstreetmap.org/way/336589435 この○○地方は行政区ではなく、行政組織が存在しないため、 そもそもadmin_levelを割り当てるのは不適切と考えています。 後ほどChangesetコメントなどにも指摘を行ってみる予定ですが、 まずはご連絡、ということでお知らせします。 ---------- Forwarded message ---------- From: johnw <jo...@mac.com> Date: 2015-08-11 20:30 GMT+09:00 Subject: [Tagging] Help undoing an admin level 3 edit to Japan To: strategy and related tools Tag discussion <tagg...@openstreetmap.org> A few months ago, someone enabled admin level 3 on regional boundaries in Japan. This is an error, but I don’t know how to deal with it. Admin level 3 boundaries are reserved for future for “states” of Japan. The regions currently have historical names, but just like “So-cal” or “New England” in the US, they are popular but administratively meaningless names, so they are not supposed to be used for any admin level. Japan has prefectures (provinces) - which are admin level 4, and are currently the highest order political boundaries in Japan. https://en.wikipedia.org/wiki/Prefectures_of_Japan ("Japan's 47 prefectures form the country's first jurisdiction and administrative division levels.”) Someone outside of Japan came along and changed it, even through it is against the information provided on the OSM wiki for Japan. http://wiki.openstreetmap.org/wiki/Japan_tagging#Boundary Japan is currently debating the creation of states by combining the tiny prefectures (probably in the next 20 years, as the population shrinks outside Tokyo) - but nothing is decided yet. http://www.clair.or.jp/j/forum/honyaku/hikaku/pdf/up-to-date_en3.pdf (scroll to the end for maps) Japan is the same size as California, and California has about the same number of counties as Japan has prefectures. They are really small. I am very uncomfortable changing admin settings for a whole country,and have never used the boundary tag, so I’m asking someone to go and remove the admin level 3 tags from the regions. It presents political boundaries that don’t exist. Would someone please remove these erroneous edits?
