$geoIntersects

Selects documents whose location field intersects with a specified GeoJSON object, useful for finding locations that intersect with specific geographical areas.

Syntax

{ <location field>: { $geoIntersects: { $geometry: { type: <GeoJSON type>, coordinates: <coordinates> } } } }

Parameters

location fieldstringrequired

The field containing the GeoJSON object

typestringrequired

The GeoJSON object type (e.g., "Polygon", "MultiPolygon")

coordinatesobjectrequired

The coordinates defining the GeoJSON object

Examples

Find stores intersecting with polygon

Find stores that intersect with a specific polygon area

Query:

db.stores.find({ location: { $geoIntersects: { $geometry: { type: "Polygon", coordinates: [[[-80.0, -75.0], [-80.0, -70.0], [-55.0, -70.0], [-55.0, -75.0], [-80.0, -75.0]]] } } } })

Output:

Documents whose locations intersect with the defined polygon

Intersection query with projection

Find intersecting locations and return only name and location fields

Query:

db.stores.find({ location: { $geoIntersects: { $geometry: { type: "Polygon", coordinates: [[[-80.0, -75.0], [-80.0, -70.0], [-55.0, -70.0], [-55.0, -75.0], [-80.0, -75.0]]] } } } }, { name: 1, location: 1 })

Output:

Limited projection of documents intersecting with polygon boundary
