GPS Exchange format (GPX) terms.
Term | Definition | Example |
|---|---|---|
Route | A route is made of Route Points between which a program must get the corresponding track from a vector map to draw it. The Route Points may be crossings or junctions or as distant as stopover towns, such as those making a trip project. Hence, such a project can be saved and reloaded in a GPX file. | |
Route Point | Waypoints representing a series of significant turn or stage points. Unlikely to have associated timestamps as they refer to hypothetical paths that have not been traveled. | |
Track | A track is made of a sufficient number of recorded Track Points to precisely draw every bend of a path on a bitmap. It is:
It is made of at least one Track Segment containing Track Points. | |
Track Point | Waypoints representing a series of significant turn or stage points that form a track. Likely to have associated timestamps as they refer to where someone has actually been (i.e. these are typically recorded on a GPS device). | |
Track Segment | A Track Segment holds a list of Track Points which are logically connected in order describing a path. 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. | |
Waypoint | An individual waypoint among a collection of points with no sequential relationship. It consists of the WGS 84 (GPS) coordinates of a point and possibly other descriptive information. Typically used to mark an individual location. |
