I'm trying to make a car offline navigation app for iOS. Now I analyze OpenStreetMap features what to use. I would like to know if there is open source solution for the following parts of app:
- best storing of geodata - do you know Spatialite? Or use standard file system?
- rendering OSM (whatever format/own?) - vector rendering, not tile's system
- routing OSM, finding shortest/fastest path
I did some experiments but if you have any experiences, i will be glad if you help me with start.
