Measure Area
This tool allows you to measure areas on the map. It works a lot like 'Measure Distance'.
After creating the first segment and clicking, two coloured segments will appear instead of one. The window that appears will display the area enclosed within the segements.
Clicking again will turn the coloured segment between the last point you clicked and the crosshair's current location into a fixed dotted segment.
To remove all segments, click the 'Measure Area' button or the 'Arrow' button.
