空港コードや位置の正しさを検証して指摘するのはとても疲れる話 (wikipedia も間違うのだ)

Wikipedia に間違いがあります! ってことに誰が驚くんだ、とは思うんだけれども。

「空港」(というか「航空」)に関する「大親分」にはいくつか機関があって、1 に ICAO、2 に IATA、3 に(アメリカなのでエラい)FAA、あとはそれらに付随するレギュレーション関係で AIP。これらから情報引っ張ってくれば絶対間違うことはない。

けど、ここから情報を「いっきょに取得」てのは出来ないわけで、だから普段は wikipedia や openflights、あるいは flight vector などなどの「オープンな」もしくは「一般向けの」サービスを利用するわけである。

openflights の airports.dat の問題について調べてるので、だったらいっそ wikipedia 全部持ってきてしまえ、とやってみたのさ。

あららぁ…、ページ間で矛盾がある箇所が何箇所かあるのね。

何をしたかといえば、「List of airports」を ICAO コード一覧から手繰るのと IATA コード一覧から手繰るのを両方やって、不整合がないかみてみたの。不整合が出たのが上のリスト。ICAO コードで紐付けていて、例えば「iata_n, iata」と2つあるのは、_n が付いた方が IATA コードから手繰ったほうで、付いてない方が ICAO コード一覧から手繰ったもの。

まだ全部みれてないけど、「Syamsudin Noor Airport」は完全に間違っている。てことは、ほかのも間違ってる可能性がある。

そうなんだけどさ、…、難しいのはここから。

あなたが住んでるのがどこかによってこれが「常識」なのかどうかは随分違ってくるんだけれど、日本に結構「軍民共用空港」ってあるでしょう? この扱いが厄介なのね。不整合リストに RJOW (Iwami Airport?) と ROIG (Ishigaki Airport?) が含まれてるけど、それが関係してないかしら、と疑ってる。ほかも結構これ関係「らしき」のがちらほら。

もうひとつ。「空港の場所」ってのは「点」ですか? の議論。実際「空港の位置といえば」の慣習がちゃんとあって、「Aerodrome Reference Point (ARP)」が空港ごとに与えられている。2次元幾何学的に滑走路群の「重心位置」で決めるんだそうな。そうなんだけどね、仮に WikiPedia が ARP に依拠せずに地図からざっくり目視で決めたとしても、実際「実用上は普通は全然困らない」。(ほんとに繊細な aviation で ARP を指さなければならないとしたら重大かもしれないが、そんなことをするヒトタチは Wikipedia なんかあてにしないから大丈夫。) けどね、困らないにしても、「空港ってとっても広い」でしょう? ちょっと大きな空港なら半径2海里くらいのサイズがあるのね空港って。つまり両端にずれてれば最大 7～8km 違う場所指しててもおかしくない。同じ空港内なのに。

Wikipedia の全ページがちゃんと AIP とかの公式なものから情報拾ってるのかどうかわからないし、仮に「ざっくり地図から」だとしても、「百科事典としての間違いとも言えないのかも」と思ったりもする。(のでこのタイプなら指摘はしないかも。)

てわけで、目がしょぼしょぼしてきた。疲れるよ、「正しい出展」探すだけでも大変なんだから。





2016-08-30記:
「間違ってます!」って言いっ放しのものなんぞ「情報とは言えない」、てことを思う日もあればそうでない日もある。人間だもの。

ともあれ、容易に解決出来るものは直接編集してしまった。こうやってメモっとかないと自分で何したかもわかんなくなるしさ。以下が、現在までに解決して直せたもの:

岩国は最近軍民共用化してる関係で、まだややこしいんじゃないかと思う。

なお、修正出来たのは今のところ全て「指し先間違い」のものだけで、ICAOコードが違う、IATA コードが違う、という問題については、ちょっとややこしい問題が多くて、ほとんど修正してない。Otú Airport は上で言及したほうだけ直してるが、多分 IATA コードもおかしい(おそらく OTU が正で OYU は誤)。インドネシアでは一気に ICAO コードが変更されたという経緯があるようだ、てのと、IATA コードと FAA コードに関してはかなり共通だが違うものも多く、混乱があり、ワタシも調べてても確定出来ないものが多く、またインドネシア以外でも ICAO コードの変更があったのではないかと思しきものもいる(Lago Agrio Airport の ICAO コードが SENL と言ってるものと SELA と言ってるものがある)。





2016-09-01記:
信頼出来る情報筋、を増やせたので確定して直せたものが増えている。

  • IATA の Airline and Airport Code Search – おそろしく使い勝手の悪いインターフェイスではあるものの、とにかく「大親分」である。(これはずっと使ってた)
  • One World – Nations Online の IATA 3-Letter Codes – あの One World。使いやすいとも言えないがともあれ「一覧」として一撃なのが貴重。One World だもん、あてになるだろう、と思ったが、少なくとも一つは問題を見つけてしまった。IATA の Airline and Airport Code Search を使う前に補助的に使うのがよい。
  • Aeronautical Information Services – National Flight Data Center (NFDC) – 名前からは伝わりにくいが本家 FAA の airport lookup サービスとして位置づけられているもの。元々は FAA とは独立してたらしい。ので FAA コードと、あれば ICAO コードの lookup には最も信頼出来る。無論原則「US向け」サービスなので、FAA が割り当ててない国(日本含む)の空港は引けない。
  • Great Circle Mapper – かなり最初から使っていたが、初見で想像したより遥かに信頼出来る。下の方に「Other Information」があってその「Sources」が AIP を指してればもう安心。

というわけで結構本質的な問題を新たに直せたものたち:

今把握している「一覧二つの主張の食い違い」で検出した問題で残ってるのは、「たぶん問題」が 19 件。まず「問題として～「件」」が意味するのは問題空港の数とは一致してない。2～3つのコードがコンフリクトしちゃってるのがある。

ほかに「扱いづらいが問題というわけではない」のが一つ。ICAO コード LFSB なんだけどこれ、フランス国内線はミュールーズ（MLH）、スイス国内線はバーゼル（BSL）、国際線はユーロ・エアポート（EAP）、なんだって。あーこんなのあるんかぁ…。(つまり ICAO コード一つに IATA コードが 3 つぶらさがってる。)

あとは Berlin Brandenburg Airport が in construction つぅことなので、コードも仮置きな可能性がないではないので、たぶん慌てて直さないほうがいいと思うの。





2016-09-01記(2):
チェックの切り口を変え、純粋に ICAO コードの重複だけ調べたら問題増量。

うち、単なる二重記載は fix。

YORV, FYKM, KDAG, AYKG, FMMT, SGAS, LLSD が新たに見つけた問題。なおこのチェックでは既知の SBUF、YTOC、VYNT も当然ヒットする。
