Hi,

You can use neo4j-spatial for this. Have a look at these 2 test cases:

https://github.com/neo4j/spatial/blob/master/src/test/java/org/neo4j/gis/spatial/TestSimplePointLayer.java
https://github.com/neo4j/spatial/blob/master/src/test/java/org/neo4j/gis/spatial/pipes/GeoPipesTest.java

Indexing is also possible(
https://github.com/neo4j/spatial/blob/master/src/test/java/org/neo4j/gis/spatial/IndexProviderTest.java),
though I thought I read somewhere that it is not recommended yet? I guess
Peter can confirm whether that's right.

Regards
Luanne
