Just wondering if you used a NoSQL graph Database for this

Hello, I was wondering if you used some sort of no sql graph db for this... This project is awesome btw

I started with PostgreSQL but finally not.
You need to have very fast access to data, and ram is far more effective.
Then I store the data (json file, or C++ serialized map<> with boost) before drawing the map. I made sometimes backups in case of if my program crashed (and kept a point to know "where/when" the program stopped).
Railway data is about 350MB (the biggest file).

You could use the map data of the routing engine itself which should be also a lot faster and outlined in #3
