OSM and Neo4j in uDig - GSoC Report, Week 6

[Carol Hansen]

Hello everyone,

What did I do this week?

• Making progress on the OSM Routing Importer:   https://github.com/GretaCB/Routing-Project/blob/dc8c4dc3b49a6927f66c1f30d8b00c2d60ade9b2/neo4j/src/main/java/org/neo4j/neo4j/OSMRoutingImporter.java
• Indexed Way Nodes by highway name (have to figure out how to test to make sure I implemented it properly)
• Researched possible Java libs I can use to calculate distance between nodes using long/lat. Will try one or two of them out today. So far I've found simplelatlng, LatLongLib, and possibly GeoTools.
• Attempted to debug my code within the second parsing method, which obtains relevant Tag element info, but still unsuccessful.
• Cleaned up my git repo.

What will I be working on next week?

• Finish up OSM Importer
• Start integrating Routing Algorithm

Did I meet with any stumbling blocks?

• I had trouble figuring out why my program is not successfully accessing relevant Tag elements or reading Node end tags within the OSM XML file. Will continue working on this.

Thank you,

Carol Hansen
