• Optional: make

How to configure

app/waypoints.json contains the gps route in JSON format. You can easily configure your own route by modifying the waypoints array.

• accuracy (in meters): minimum GPS accurracy required before the GPS locations is considered as valid. i.e. as long as the GPS error is greater than this value, it is assumed you don't have a position fix.
• tolerance (in meters): tolerance of GPS position in respect to waypoint. i.e. if GPS position gets closer than this value to the current waypoint, it is assumed you have arrived.
• maxAge (in seconds): maximum age of a GPS position. i.e. if last GPS reading is older than this amount of seconds, it is assumed you have lost signal and your position is no longer valid.
• waypoints: array of waypoint coordinates for the route. Each waypoint has two values, defining its position in the WGS 84 coordiate system, a.k.a. regular GPS coordinates.
  • latitude (in decimal degrees)
  • longitude (in decimal degrees)
