How do I add a GPX file to Google Maps
The map data format most commonly used by Google Maps is KML, but Google Maps also supports many other formats, including GPX.
GPX, also known as GPS eXchange format, is an open standard XML format that contains Global Positioning System (GPS) coordinates on top of additional map data. The format has seen increasing growth and is being adopted by many manufacturers as their preferred native format, regardless of device.
Think of GPX the way you would think of an image file format like JPG or PNG. There is no universal standard for an image file, but most people prefer JPG or PNG over any other available format. They are the easiest to use and are accepted on almost all platforms.
