-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi folks. A few months ago, someone pointed me to Neo4J Spatial, though I haven't seriously investigated it until now. I have a few questions both about how to get started, as well as about what is and isn't possible.
I'm currently working on a web-based (and hopefully embedded at some point) GPS navigation platform based on OSM data. The codebase is at a fairly advanced state, but I'm starting to run up against the limits of my data model. In particular, I'm encountering the following issues which I'm wondering if Neo4J Spatial can help with: My database is currently H2 with no geospatial extensions whatsoever, so I'm finding it very hard to, say, list the ten nearest points to a given location, ten more beyond that, etc. as all I'm doing is increasing the bounds on an arbitrary box and taking whatever that returns. Is this something that Neo4J can do well? It seems like a graph database would be specialized at these sorts of queries, but I could be wrong. I think I have a basic understanding of how graph databases work, but could someone relate that to how Neo4J Spatial would import OSM data? Are OSM nodes directly imported into Neo4J nodes, with ways modeling the relations between them? Or is there another scheme? I think it would really help if I can import and play with live data. Where can I find the simplest possible code to import OSM data into a Neo4J Spatial database? And, once done, how can I best play with that data? Does the shell support spatial queries? Thanks in advance. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk1eBd4ACgkQIaMjFWMehWJ3eQCeMgpp8EgHM/ek8vnqf43E3gXN 9qEAniv56B16lZnPtFblr1AfLPr7mfFD =DJt3 -----END PGP SIGNATURE----- _______________________________________________ Neo4j mailing list [email protected] https://lists.neo4j.org/mailman/listinfo/user
