我已经从oracle将多边形导出到mongodb中。现在我试图实现这样的事情（以下查询在oracle空间中工作）。
select * from geoloc g
where SDO_CONTAINS(
g.geoloc,
SDO_GEOMETRY('POINT(-77.44848485115146 38.94291436764032)',8307)) = 'TRUE'
这样我就可以获得包含所提供点的所有多边形。
多边形如下：
{
"_id" : "4c103c0f-4dc6-4bfa-88f4-712bb498ce39",
"loc" : {
"type" : "Polygon",
"coordinates" : [

根据外观，您需要geoIntersects operator。
考虑以下
//Add setup data
db.polygon.insert({ "_id" : "Poly1", "shape" : { "type" : "Polygon", "coordinates" : [ [ [ 0, 0 ], [ 3, 0 ], [ 3, 3 ], [ 0, 3 ], [ 0, 0 ] ] ] } })
db.polygon.insert({ "_id" : "Poly2", "shape" : { "type" : "Polygon", "coordinates" : [ [ [ 3, 0 ], [ 6, 0 ], [ 6, 3 ], [ 3, 3 ], [ 3, 0 ] ] ] } })
//Create a 2dSphere index
db.polygon.ensureIndex({shape:"2dsphere"})
然后我可以运行以下查询：
db.polygon.find( { shape : { $geoIntersects : { $geometry : { type : "Point", coordinates: [ 3, 1 ] } } } } )
这将返回包含点3,1的所有多边形，包括仅边缘匹配的多边形（在这种情况下，两个文档都具有边缘运行3,0＆lt; - ＆gt; 3,3）
