ArangoDBでGeoJSONを試す
ArangoDBでGeoJSON
にチュートリアル的なのがあるので試してみた
GeoJSONとは
地理的データをエンコードするためのフォーマットです
新潟のGeoJSONデータ
から落とせます
落としてきたデータをインポートする
上記画像のようにfeaturesの中身をコピーして
WebUIで任意のコレクション(今回はniigata)の右上の＋をクリックして
このようにDocumentBodyに貼り付けCreateをクリック
データが作られた
WebUIで出してみる
QUERIESで
FOR u IN niigata
FILTER u.properties.KEN_NAME == "新潟県"
AND u.properties.GST_NAME == "長岡市"
RETURN u
結果
長岡市の範囲が出た！
指定座標(緯度経度)で範囲内データを取得する
自由の女神の位置から
// GEO_POINT(経度, 緯度)
LET statueOfLiberty = GEO_POINT(-74.044500, 40.689306) // 自由の女神
FOR u IN niigata
FILTER
GEO_CONTAINS(u.geometry, statueOfLiberty) == TRUE
RETURN
u
