Location query - reverse search (lat-lon to location)

We would like to add a support to our API that for a given WGS84 coordinates, it will response with whats in that location.
For example, for a given (-118.30724539059837, 33.71618286284796) coordinates, It will response with geojson like so:

まず、この issue にすでにリンクされているオープンな pull request #71 を確認します。その実装を、要求されている WGS84 座標入力および GeoJSON のレスポンス例と比較してください。API が逆ジオコーディングによる位置検索をサポートし、要求されたレスポンス形式を返せば完了です。
