GPX, or GPS exchange format, is an XML file format for storing coordinate data. It can store waypoints, tracks, and routes in a way that is easy to process and convert to other forms. All GPS data used by OpenStreetMap is converted to GPX format before it can be uploaded.

Example

The following file extract shows an example of how a single waypoint (called 'LAGORETICO') and a series of track points are represented in the GPX file.
