優れた無料の逆ジオコーディングAPIを探しています
私は2つの逆ジオコーディングAPI（Google Mapsとfoursquare）に精通しています。どちらにも問題があります。 lat、lng = 35.699,139.707（東京）を考えてみましょう。
Foursquare：

response.venues[0].location.cityエントリにのみ興味があります。残念ながら、私は日本語がわからないので、それが何であるかわかりません。ええと、グーグルはそれが東京の特別な区の1つである新宿だと言います。

Google Maps APIは英語ですが、結果が低すぎます。たとえば、都市や町は通常、localityタイプで識別されます。ここでの産地は東京の特別区のひとつである新宿ですが、それは東京の行政システムの実施の詳細です。東京を街にしたいと思っています。もちろん、東京は実際には日本の都道府県の1つであることがわかっているので、localityの代わりにadministrative_area_level_1タイプのトークンを検索することもできます。
Foursquare APIにも同じ問題があり、都市は新宿、州は東京として報告されますが、どちらも日本語のみです。
常識的な結果を返す単純な高レベルの逆ジオコーディングAPIはありますか？つまり、「新宿に行く」というのは海外では誰もいません。 「東京に行く」と言われます。
ありがとう。
Yahoo Maps API は、精度を設定する機能を提供するため、役立つ場合があります。
OpenStreeMapには逆引き参照ツールもあります。

GeocodeFarm を試してください。
IPベースごとに1日あたり250の無料クエリがありますが、Webサービスは無制限で無料で、25ドルという安い価格で1日あたり25,000のクエリが提供されます（これは私のアプリで使用しています）。
結果は理解しやすく、完全な文書化、順方向と逆方向などです。
Bing Mapsを試すことができます。正確さはわかりませんが、試すことができます。
