Thanks Michael. I will try this.
I tried the following and getting an error while adding the
SpatialDatabaseRecord to the Spatial Index Impl.
The error is
Caused by: javax.transaction.RollbackException: Tx status is:

IndexImplementation indexImpl = new SpatialIndexImplementation
(graphService);
Index<Node> nodeIndex = indexImpl.nodeIndex("Geocode",
SpatialIndexProvider.SIMPLE_WKT_CONFIG);
Iterable<Node> allNodes = graphService.getAllNodes();
for(Node node: allNodes){
Transaction tx = graphService.beginTx();
try{
if(node.hasProperty("addressLine1")){
Node added = graphService.createNode();
added.setProperty("wkt", node.getProperty("wkt"));
System.out.println("Adding node " + added.getId());
nodeIndex.add(added, "addressLine1",
node.getProperty("addressLine1"));
}
}catch(Exception e){
e.printStackTrace(System.out);
tx.failure();
}
tx.success();
