GPX(
GPS Exchangeformat, GPS interchange) is a universal GPS data format designed for application software in an XML format.
It can be used to describe road points, trajectories, distances. This format is free and can be used without the need to pay any license fees. Its label saves location, elevation and time, which can be used to exchange data between different GPS devices and software. In GPX, a collection of points that have no sequential relationship, called a route point. A set of ordered points is called a trajectory or a distance . The trajectory is a record that a person has traveled, and the distance is a suggested place to go next. So, in general, the points in the trajectory, including time information, points in the distance, no time information. The smallest GPX file contains only one point of latitude and longitude coordinates, and the others are optional.
