Differential Leveling
Introduction
This interactive simulation will introduce you to the iterative 4-step process of differential leveling:
- take a backsight measurement (BS)
- move the rod
- take a foresight measurement (FS)
- move the instrument
At each turning point (TP) you will calculate the height of the instrument (HI) and the elevation (Elev) for that point.
Learning Objectives
Upon completion of this simulation, you will be able to:
- Determine the elevation of a Temporary Benchmark (TBM)
- Calculate the Height of the Instrument and Elevation at a Turning Point
- Identify when to take a Backsight or Foresight measurement
- Choose when the measuring rod should be moved versus when the instrument should be moved
