查找给定的经度，纬度对是否位于MongoDB中的任何多边形中 [英] Find if given longitude, latitude pair lies in any of the polygon in MongoDB

问题描述

根据我目前对MongoDB的理解，我们通过传递[long，lat]对数组的数组来搜索集合，以检查该文档的[long，lat]对是否退出坐标[[ [], [], [] ]]内.

As per my current understanding on MongoDB we search our collection by passing an array of [long, lat] pair arrays, to check if that document's [long, lat] pair exits inside the coordinates [[ [], [], [] ]].

i.e

db.SomeCollection.find({
    "location":{
        $geoWithin: {
            $geometry: { 
                type: "Polygon", 
                coordinates: [
                    [[1, 2], [1, 3], [1, 4]],
                    [[2, 5], [2, 6], [2, 7]]
                ] }
        }
    }
})

我要寻找的是我需要将[long，lat]对输入到包含固定多边形Geofence数组的文档中，并得出结论[long，lat]对是否存在于那些[Polygonal Geofence数组]中.

What i am looking for is that i need to feed the [long, lat] pair to a document containing fixed Polygonal Geofence arrays and conclude if the [long, lat] pair exists inside any of those [Polygonal Geofence arrays].

在MongoDB中有可能吗?我的问题有效吗?

Is this possible in MongoDB? Is my question valid?

请注意:我是MongoDB以及地理空间数据的新手，因此 如果问题包含错误的术语，请原谅.

Please Note: I am novice to MongoDB as well as Geospatial Data hence forgive if the question contains wrong terminologies.

推荐答案

几天后，我回到我的问题中，找到了答案.

After few days I am returning to my question as i found the answer to it.

该解决方案发布在此处是Jacob Ribnik

因此，将其实施到我的问题中将如下所示:

hence implementing it to my problem it would be something like below:

db.Poly_Geofence_collection.find(
{
    "location": {
        $geoIntersects: {
            $geometry: {
                type: "Point",
                coordinates: [1,1]
            }
        }
    }
});

我的Poly_Geofence_collection集合的外观如下:

{
    "_id": ObjectId("SomeRandom12ByteObjectId"),
    "location" : {
        "type" : "Polygon",
        "name" : "Location Name",
        "coordinates" : [
            [
                [0, 0], [1, 2], [1, 1], [2, 1], [0, 0]
            ]
        ]
    }
}
