![]() People not so used to map reading may well prefer to use routes. I prefer to plot my walks as tracks and look at the line of the planned path directly on the map on the device and don't therefore need direction arrows or proximity beeps. Tracks are simpler and can be much, much longer with thousands of track points. Routes are limited to the number of waypoints that your device can support and this may vary depending on whether you are using direct routing or routing preferences according to an activity profile. I believe that the Ordnance Survey Mapping app (and others) always exports GPX files as routes since it presumes you want to use it to navigate turn-by-turn, even if they are originally uploaded as tracks and thus converts all the track points to waypoints. Conversely, the waypoints in a route are converted to track points with no routing information. The track points in a track are converted to routable waypoints. You can also convert between tracks and routes in programs like Garmin BaseCamp. Many downloadable GPX files are just that - a track recording of that individual's walk. ![]() Of course if your GPSr is set to record, you will capture the track of where you and your GPSr actually went. ![]() You can generate a track by plotting an intended route over a digital map or over aerial imaging such as in Google Earth. Tracks are just a set of linked points defining a path, just like drawing a pencil line on a paper map. The non-alerting points are called shaping points, since that is all they do (they won't beep or display a turn arrow).Ī track is simply a set of track points with no routing or navigation that cannot be used in your GPSr to provide turn-by-turn assistance. ![]() You can therefore download someone else's GPX file which may contain a route or a track and before use, you should know which type you have as they are handled differently by your GPSr.Ī route contains a series of waypoints that are navigated in turn to take you along a walk, of which some or all will be alerting when such a route is being navigated using the GPS receiver (a bit like a car satnav). You can plan a walk either as a route or a track and either will be contained in a GPX file which you upload to your GPS receiver. ![]() Garmins take on Routes and Tracks is here: but this omits the use of tracks to plan walks. ![]()
