Since there is no standard data format for the storage and exchange of GPS data, the GPX file was developed by the company Topografie. As with most other data formats, the XML schema is used, which describes the elements and the structure of the GPS format. As the name GPX already describes, the abbreviation at the end of the file is .gpx. The format is publicly accessible, license-free and free to use by anyone. In addition to the known GPS data, additional metadata can also be inserted in a GPX file. Due to the ever increasing number of software systems, “Google Earth”, “MagicMaps” or “Touratech QV” can now also access this data and import it into the systems. The data can not only be imported but also created via Google Maps and then exported as a GPX file.
