I have a postgreSQL db with nodes (lat,long,id,edge count)(Only tower nodes are stored) and edges (id,startnode,endnode), originally extracted from an osm file, how would it be possible to use these for map matching?
Is it correct to say that it is not possible to use the database directly even if I would generate virtual nodes since accessing it is too slow in comparison to the data structures normally used?
Instead I can make a reader like reader-osm but from my db and use dummy data for the missing information (make all roads car roads for example.)?
Or is there a better solution?
Thank you in advance!
