JTS does not have a spatial index -- it is good for spatial operations (check if some shape is within/intersects/etc another shape) In Neo4j, they use JTS to build an RTree that is stored in their native graph format: https://github.com/neo4j/neo4j-spatial/blob/master/src/main/java/org/neo4j/gis/spatial/RTreeIndex.java Building an RTree in lucene is a bit more difficult since we can not easily update the value of a given field. I'd like to figure some way to do this though. ryan --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
