Definition of Navigation Terms
The term ‘Waypoint’ is quite traditional and derives from the aviation and marine industries where it refers to a ‘series of points along a route’. The same definition applies in GPS navigation and in traditional route preparation.
Wiltshire Walks uses two types of Waypoint - Invisible and Visible. Invisible Waypoints are used to help define a Route onto a Map allowing bends and curves. These can also be programmed into a Handheld GPS allowing the walker to follow the ‘real’ route on the ground. Visible Waypoints can be anything along a route - e.g., an intersection of tracks, a gate or stile, a natural feature, a ‘Point of Interest’ , a viewpoint or vantage point, a sharp bend, etc.
Visible Waypoints are shown on all our Maps and Routecards and often divide a Route into segments or legs.
Routes are a series of Waypoints that make-up an exact route, or segment of a route. In general preparation work a Route is the course that is desired.
In modern navigation terms, a Track consists of Waypoints that have been taken during a journey. If perfect, then a Track could be deemed a Route. However, this is rarely the case as most exploratory journeys will contain mistakes, back-tracks, and perhaps intentional meanderings.
Tracks are often used in conjunction with map-derived Waypoints to make a new set of Waypoints to produce a desired Route.
