The GPS eXchange format, also known as GPX, acts as an XML-based schema that GPS software applications use to read data. An XML file contains instructions in text format that follow specific programming rules to control differing elements and attributes. GPX files store waypoints, tracks and routes. You can open these files to view the information in any text reader, or import the data into a GPS software application to see detailed, graphic information that includes locations, elevation and time stamps. Use this information to mark maps, find geolocation information and tag photographs.
