• Measuring distances, angles and areas on the map screen:
Use the three icons in the right-upper corner. The upper
one is for distances, the second one for areas and the
lower one for angles.
For each tool, the first click on the icon will activate the
tool and change the cursor shape. The second click will
turn off the tool and the cursor will recover its initial
shape. You may also press the right-hand mouse button to
deactivate the tool.
Distance measurement:
– Click on the first point from where to start the distance
measurement.
– Click on the second point defining the first measured
segment. Any new click on the map will create a new
segment from the previous point. From the second
point, the indicated distance value stands for the total
distance measured from the start point.
– Anticipate the end of measurement by double-clicking
on the last point. This will freeze the distance
measurement.
– Click on to quit the distance measurement tool.
Area measurement: Same as distance measurement. The
area measurement is effective only after you have defined
three points on the map. The value of perimeter is also
provided.
Angle measurement:
– Click successively on the first then on the second point
defining the segment providing the reference
direction. The tool then draws the angle measured and
gives its current value as you move the mouse cursor
on the map screen. If you click anywhere, the tool
freezes on the angle defined by this last click and gives
its value.
