spatial.intersects

Procedure

Returns all geometry nodes that intersect the given geometry (shape, polygon) in the layer

Signature

spatial.intersects(layerName :: STRING, geometry :: ANY) :: (node :: NODE)

Input parameters

Name Type Default Description

layerName

STRING

null

The name of the layer

geometry

ANY

null

A WKT string or a coordinate. A valid value for the coordinate is a:

  • JTS Coordinate

  • Neo4j Coordinate

  • Neo4j Point

  • Map with keys 'latitude' and 'longitude'

  • Map with keys 'lat' and 'lon'"

  • Node or Relationship with properties 'latitude' and 'longitude'

  • Node or Relationship with properties 'lat' and 'lon'

Output parameters

Name Type Description

node

NODE

Examples

Find geometries in a polygon

CALL spatial.addPointLayer('geom')
UNWIND [ {name:'a',latitude:60.1,longitude:15.2}, {name:'b',latitude:60.3,longitude:15.5} ] as point
CREATE (n:Node)
SET n += point
WITH n
CALL spatial.addNode('geom',n) YIELD node
RETURN node.name as name
