There are three measurements you can make.
1. The horizontal width as measured by the ruler.You can drag the ruler to get a surveying
measure of the structure´s base.
2. The vertical height as measured by the ruler. Click on “ Vertical” and then drag the ruler to get
a surveying measure of the structure´s height.
3. The actual width of the base. Press “Walk base” and the person will report the base (in feet)
of the structure.
You now have three measurements, including a ratio of height and width. Calculate an
estimated height of the structure (in feet) and enter it to the nearest foot. Then press “Check.”
