Chapter 5 Differential leveling
Profile leveling is very similar to differential leveling. Both profile and differential leveling use backsights, foresights, benchmarks, and turning points.
For differential leveling, the only critical feature of station identification is that an organized method be used so that the system is clear to the user of the notes.
In differential leveling, each station is used as a backsight and a foresight.
As in differential leveling, the sights should be balanced, if possible.
