$geometry¶
- $geometry¶
New in version 2.4.
Changed in version 3.0: Add support to specify single-ringed GeoJSON polygons with areas greater than a single hemisphere.
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> ] }
New in version 3.0: 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 you use longitude and latitude, specify coordinates in order of: longitude, latitude.
