A GPX file, or GPS Exchange Format file, is a text file that contains geographic information such as waypoints, tracks, and routes saved in it. It is an open standard used by many GPS programs and can be used to save, send, and upload routes that can be used by many GPS programs or devices. The file format is called an "open standard" meaning that it can be used on any device for free regardless of brand. The required data for a GPX file includes longitude and latitude location data that may include waypoints, routes, and tracks. The file can be opened with any text editor or word processor, and there are also more sophisticated tools that offer mapping and are easier to work with. GPX files are used to exchange GPS location data, including maps, routes, and geocaching information, with others. Most commonly, fitness devices and applications, such as Garmin Connect devices, use GPX files to import and export running and biking routes. More sophisticated mapping applications, including the desktop versions of Google Earth Pro and the web version of Google Maps, also create and use GPX files.
