$geometry

$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.

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

• Valid longitude values are between -180 and 180, both inclusive.

• Valid latitude values are between -90 and 90, both inclusive.
