To find square area data from mongodb Query using 2 google map point (latitude and longitude)

问题

I am working on mongodb Geospatial feature.

Following is my db schema

{
    _id:5c6fea5aa7f54038cc63db92,
    location:{
        coordinates:[-96.81916,33.07516],
        type:"Point"
    },
    userId:1
}

Indexing on location field with 2dsphere

I have 2 point and each one have latitude and longitude and its example is below

sw_latitude: 32.76286484066411 sw_longitude: -96.91870791625979

ne_latitude: 32.789133220783015 ne_longitude: -96.67529208374026

base on these 2 points i need to get all userId which are cover in these 2 points square

Can you please suggest me mongo query which give me result?

回答1:

I tried many way and finally i got one solution

Step for solution 1:

Step 1: find boundary from that 2 point

latitude:[32.740776 TO 32.8112099] AND longitude:[-96.910983 TO -96.683016]

Step 2: use $box from Geospatial (ref: $box from mongo) and pass this boundary point in that..

{    location: { 
       $geoWithin: { 
           $box:  [ [ 32.740776, 32.8112099 ], [ -96.910983, -96.683016 ] ] 
        }     
      } 
}

Step for solution 2:

Step 1: setup existing point proper way as following

latitude:[32.76286484066411 TO 32.789133220783015] AND longitude:[-96.91870791625979 TO -96.67529208374026]

Step 2: use $box from Geospatial (ref: $box from mongo) and pass this boundary point in that..

{    location: { 
       $geoWithin: { 
           $box:  [ [ 32.76286484066411,  32.789133220783015 ], [ -96.91870791625979, -96.67529208374026 ] ] 
        }     
      } 
}

Hope will be helpful for you
