geoIntersects

abstract fun Field<T, Geo>.geoIntersects(geometry: Geo)(source)

open fun KProperty1<T, Geo>.geoIntersects(geometry: Geo)(source)

Matches documents whose geospatial data intersects with the given geometry.

Example

class GasStation(
    val _id: ObjectId,
    val name: String,
    val loc: Geo.Point,
)

gasStations.find {
    GasStation::loc.geoIntersects(
        Geo.LineString(
            Geo.Point(Longitude(-105.82), Latitude(33.87)),
            Geo.Point(Longitude(-106.31), Latitude(35.65)),
            Geo.Point(Longitude(-107.39), Latitude(35.98)),
        )
    )
}

Indexing

This operator does not require a 2dsphere index. However, such an index is recommended for performance.

abstract fun Field<T, Geo>.geoIntersects(polygon: Geo.Polygon, crs: Geo.CoordinateReferenceSystem? = null)(source)

open fun KProperty1<T, Geo>.geoIntersects(polygon: Geo.Polygon, crs: Geo.CoordinateReferenceSystem? = null)(source)

Matches documents whose geospatial data intersects with the given polygon.

Indexing

Big polygons

For queries that specify a polygon with an area greater than a single hemisphere, the default crs results in queries for the complementary geometry.

In these cases, specify a crs of Geo.CoordinateReferenceSystem.MongoDB. Only single-ringed polygons are supported.
