Examples

Create a native point layer

CALL spatial.addNativePointLayerXY('geom','x','y')
Table 1. Result
node 
(:SpatialLayer {
    geomencoder: "org.neo4j.gis.spatial.encoders.SimplePointEncoder",
    geomencoder_config: "x:y",
    index_class: "org.neo4j.gis.spatial.index.LayerRTreeIndex",
    layer: "geom",
    layer_class: "org.neo4j.gis.spatial.SimplePointLayer"
})

create a node and add it to the index

CREATE (n:Node {id: 42, x: 5.0, y: 4.0}) WITH n CALL spatial.addNode('geom',n) YIELD node RETURN node

Find node within distance

CALL spatial.withinDistance('geom',point({latitude:4.1,longitude:5.1}),100)
Table 2. Result
distance node 
15.705713907526011
 
(:Node {
    bbox: [ 5.0, 4.0, 5.0, 4.0 ],
    gtype: 1,
    id: 42,
    x: 5.0,
    y: 4.0
