Spatial functions

point({x: $x, y: $y})

Returns a point in a 2D cartesian coordinate system.

point({latitude: $y, longitude: $x})

Returns a point in a 2D geographic coordinate system, with coordinates specified in decimal degrees.

point({x: $x, y: $y, z: $z})

Returns a point in a 3D cartesian coordinate system.

point({latitude: $y, longitude: $x, height: $z})

Returns a point in a 3D geographic coordinate system, with latitude and longitude in decimal degrees, and height in meters.

distance(point({x: $x1, y: $y1}), point({x: $x2, y: $y2}))

Returns a floating point number representing the linear distance between two points. The returned units will be the same as those of the point coordinates, and it will work for both 2D and 3D cartesian points.

distance(point({latitude: $y1, longitude: $x1}), point({latitude: $y2, longitude: $x2}))

Returns the geodesic distance between two points in meters. It can be used for 3D geographic points as well.
