Map matching track coordinates to OpenStreetMaps

Snap GPS track data to the roads in OSM with a fast and free algorithm. Build a simple Android test App that uses GraphHopper’s map-matching module (GitHub: [login to view URL]) or something like GMmaps SnapToRoad (but free) or similar to quickly snap a track lat/long data to the nearest road in OpenStreetMap. Similarly to what is described in the map-matching/README.md. The app will: - Read the track data from the attached DB: table tbl_distance, fields trip_lat & trip_long. (The track data will later be changed to test the app.) - Snap the data to OpenStreetMap roads saving the snapped positions to the same DB: fields lat_ok, long_ok & road_name - Fill in the DB fields: road_name, Municipality, Highway, MaxSpeed - Paint the original track and the snapped one in a map in different colors - Do the snapping with a locally downloaded copy of OpenStreetMap Spain. No online queries to web services of graphhopper, OSM or others. I have some basic incomplete & very slow code loading the local map and painting the track available in: [login to view URL] The task now is to snap the DB data to OpenstreetMap roads saving the snapped position to the DB and adding also in the DB the road name, type, maxspeed and city. In order to test the app, you need to copy a folder to the location on Your phone that is created when app is first installed. That location is: [download-folder]/graphhopper/maps, where the download-folder can e.g. be /mnt/sdcard/download or /storage/sdcard/Download/ The mentioned folder with OSM generated for Spain.
