Module `Gpx.Waypoint`Source

GPS waypoint data and fix types

The Waypoint module handles individual GPS points, including waypoints, route points, and track points. Each waypoint contains:

Required coordinates (latitude/longitude)
Optional elevation in meters above mean sea level
Optional timestamp
Optional metadata like name, description, symbol
Optional GPS quality information (accuracy, satellite count, etc.)

Fix types indicate GPS quality: none, 2D, 3D, DGPS, or PPS.

Waypoint data and GPS fix types

Sourcetype fix_type =

| None_fix
| Fix_2d
| Fix_3d
| Dgps
| Pps

GPS fix types as defined in GPX spec

Sourcetype t = {

lat : Coordinate.latitude;
lon : Coordinate.longitude;
ele : float option;
time : Ptime.t option;
magvar : Coordinate.degrees option;
geoidheight : float option;
