How to understand Neo4j spatial nodes after importing from OSM file

Question

I have imported an OSM file to Neo4j, When I try to find nodes near by one location, I used
CALL spatial.closest("sg_osm",POINT({longitude:103.9451838,latitude:1.352351217}),0.0001)

Below is the response node, how do I understand this node as there is no lat/lon as the property, what does this node mean ? and gtype 2? If I want to search this node, what will be my cypher query?

{
  "vertices": 25,
  "gtype": 2,
  "bbox": [
    103.9441967,
    103.9452897,
    1.3520486,
    1.3530789
  ]
}
