GPX

GPX stands for GPS Exchange Format. It allows people to exchange data about:

• Waypoints
• Tracks
• Routes

Geocachers use GPX files to download cache coordinates into their GPS receiver. This saves the hassle of entering coordinates of each cache into their GPS receiver.

The normal process it to download waypoints from a cache listing website into waypoint management software on your PC, and then download the waypoints into your GPS.

GPX was developed by Topografix, which publishes the GPX format specfication.
