navigational track format (Mapping Toolbox)

Describe waypoints of a navigational track

Description

Track waypoints put into latitude and longitude column-vectors are said to be in navigational track format. Waypoints are points through which a track passes, usually corresponding to course or speed changes. A navigational track is made up of the line segments connecting these waypoints, which are called legs. In navigational track format, n legs are described using n+1 waypoints.

For Mapping Toolbox navigation functions, angle units are always in degrees. See the section entitled "Conventions for Navigational Functions" in Chapter 5 of the Mapping Toolbox User's Guide for more information on unit formats for navigation functions.

Examples

The waypoints of the following track, in navigational track format, are:

waypoints = [36 -5; 36 -2; 38 5; 38 11; 35 13; 33 30; 31.5 32]
waypoints =
   36.0000   -5.0000
   36.0000   -2.0000
   38.0000    5.0000
   38.0000   11.0000
   35.0000   13.0000
   33.0000   30.0000
   31.5000   32.0000
