This map implements a Google maps style measurement tool.
To start measuring, right click the map and choose “Measure distance”.
Left click the map, and the measurement between the two locations will display. Keep clicking to add more measurement waypoints.
To remove a waypoint, left click on the waypoint (the first point cannot be removed).
To insert a waypoint on the measurement line, left click the line. Waypoints can be moved by clicking and dragging them.
If you draw a polygon then when the first point and the last point are close enough an area value will display.
To end measuring, right click the map and choose “Clear measurement”.
