爲什麼我會得到以外的多邊形值與geoIntersect

Question

我使用MongoDB的存儲與幾何形狀在這種格式

"geometry" : { "type" : "Polygon", "coordinates" : [ [ [ 2.0315, 85.8546219515 ], [ 2.0315, 86.1673780485 ], [ 1.7185, 86.1673780485 ], [ 1.7185, 85.8546219515 ], [ 2.0315, 85.8546219515 ] ] ] } 

我試圖使用geoIntersect和使用這樣的查詢矩形多邊形多邊形：

find({geometry:{$geoIntersects:{$geometry:{"type": "Polygon", "coordinates":[ [[12,20], [13,20], [13,18], [12,18], [12,20]]]}}}}) 

當我做小查詢那樣，結果都很好，但是當我擴大到真正的大箱子：

find({geometry:{$geoIntersects:{$geometry:{"type": "Polygon", "coordinates":[ [[-166.2890625,46.55886030311719], [-166.2890625,47.39834920035926], [12.12890625,47.39834920035926], [12.12890625,46.55886030311719], [-166.2890625,46.55886030311719]]]}}}}) 

然後我開始變得非常奇怪的結果一樣

"geometry" : { "type" : "Polygon", "coordinates" : [ [ [ 2.9684999999999997, 85.54162195149999 ], [ 2.9684999999999997, 85.8543780485 ], [ 2.6555, 85.8543780485 ], [ 2.6555, 85.54162195149999 ], [ 2.9684999999999997, 85.54162195149999 ] ] ] } 

我只返回從數據庫實際上是我的輸入多邊形內部的幾個多邊形（共4個）：

"geometry":{"type":"Polygon","coordinates":[[[12.343499999999999,47.1416219515],[12.343499999999999,47.454378048500004],[12.0305,47.454378048500004],[12.0305,47.1416219515],[12.343499999999999,47.1416219515]]]}} 
"geometry":{"type":"Polygon","coordinates":[[[12.343499999999999,46.829621951499995],[12.343499999999999,47.1423780485],[12.0305,47.1423780485],[12.0305,46.829621951499995],[12.343499999999999,46.829621951499995]]]}} 
"geometry":{"type":"Polygon","coordinates":[[[-166.0935,46.5166219515],[-166.0935,46.829378048500004],[-166.4065,46.829378048500004],[-166.4065,46.5166219515],[-166.0935,46.5166219515]]]}} 
"geometry":{"type":"Polygon","coordinates":[[[-166.0935,46.829621951499995],[-166.0935,47.1423780485],[-166.4065,47.1423780485],[-166.4065,46.829621951499995],[-166.0935,46.829621951499995]]]}} 

我不應該在我的意見中，有八十年代的任何緯度。我不知道這些來自哪裏。它們構成返回的大部分。 （847/851結果）

Answer 1

我不認爲多邊形適合一個半球。從$geoIntersects docs,

用GeoJSON指定爲$ geoIntersects查詢的任何幾何都必須適合單個半球。
