$geometry (original) (raw)

$geometry

The $geometry operator specifies a GeoJSON geometry for use with the following geospatial query operators:$geoWithin, $geoIntersects, $near, and$nearSphere. $geometry uses EPSG:4326 as the default coordinate reference system (CRS).

To specify GeoJSON objects with the default CRS, use the following prototype for $geometry:


$geometry: {

   type: "<GeoJSON object type>",

   coordinates: [ <coordinates> ]

}

To specify a single-ringed GeoJSON polygon with a custom MongoDB CRS, use the following prototype (available only for $geoWithin and$geoIntersects):


$geometry: {

   type: "Polygon",

   coordinates: [ <coordinates> ],

   crs: {

      type: "name",

      properties: { name: "urn:x-mongodb:crs:strictwinding:EPSG:4326" }

   }

}

The custom MongoDB coordinate reference system has a strict counter-clockwise winding order.

Important

If specifying latitude and longitude coordinates, list thelongitude first, and then latitude.
