a track is made of a sufficient number of trackpoints to precisely draw every bend of a path on a bitmap.For example, each point in a track may have a timestamp (because someone recorded where and when they were there), but the points in a route are unlikely to have timestamps (other than estimated trip duration) because route is a suggestion which might never have been traveled. To represent a single GPS track where GPS reception was lost, or the GPS receiver was turned off, start a new Track Segment for each continuous span of track data.Ĭonceptually, tracks are a record of where a person has been and routes are suggestions about where they might go in the future. A Track Segment holds a list of Track Points which are logically connected in order. trkType is a track, made of at least one segment containing waypoints, that is, an ordered list of points describing a path.rteType is a route, an ordered list of routepoint (waypoints representing a series of significant turn or stage points) leading to a destination.It consists of the WGS 84 (GPS) coordinates of a point and possibly other descriptive information. wptType is an individual waypoint among a collection of points with no sequential relationship.Additional data may exist within every markup but is not shown here: Ellipsis (.) means that the previous element can be repeated. The required data for a GPX file can be seen below. ![]() Waypoints, routes and tracks recorded by GPS receivers.
