Experiment 3 - Obstacle to both chaining and ranging
Obstacle to both chaining and ranging
A building is the typical example for this type of obstacle. Select two points A and B on one side of the obstacle. Erect perpendiculars AC and BD of equal length. Join CD and prolong it past the obstacle. Choose two points E and F on the line CD and erect perpendiculars EG and FH equal to that of AC or BD. Join GH and prolong it. Measure DE. BG = DE.
