Importance of GPX Files on Trekking – A Complete Guide
GPX stands for GPS Exchange format file, which is an open standard used by many GPS programs, computer software, and on the web. It is simply a text file with geographic information such as waypoints, tracks, and routes saved in it. The GPX files can be used to save, send and upload routes that can be used by many GPS programs.
Trekkers really want to know the importance of a GPX file on the trek. It can save your life on a trek or on camping. If you are going with a trekking guide or an organization, it is useful to have this knowledge. A small simple file or a tracking device guides your safety on the trek and makes it essential for anyone going on the trek.
GPX files are stored in WGS 84 format. It has a decimal equivalent of latitude and longitude. A coordinate in WGS 84 is -77.508333, and in latitude would be S 77° 30′ 29.9988″ (degrees minutes seconds). Any unit that uses the GPS satellites will expect the GPX data in this WGS 84 format.
Three types of data are stored in GPX files:
Waypoint – Waypoint is the GPS coordinates of a point. It may also include other descriptive information.
Route – Route is a list of track points, which are waypoints for a turn or stage points, that lead to a destination. It is made of route points between which a program must get the corresponding track from a vector map to draw it. The route points may be crossings or junctions or as distant as stopover towns on the trip project
Track – Track is a list of points that describe a path. This is made of an adequate number of track points to exactly draw every bend of a path on a bitmap.
