Detailed Description

The RTreeIndex is the first and still standard index for Neo4j Spatial. It implements both SpatialTemporalIndexReader and SpatialTemporalIndexWriter for read and write support. In addition it implements SpatialTreeIndex which allows it to be wrapped with modifying search functions to that custom classes can be used to perform filtering searches on the tree.
