Differential Leveling
HI = Elevation + BS
Elevation = HI - FS
Check: Sum BS - Sum FS = Final Elev - Starting Elev
Leveling Calculator
Enter benchmark elevation, backsight, and foresight readings to compute the height of instrument and point elevations.
Format: BS,reading or FS,reading or TP (auto: FS then BS). Example: BS,4.52 then FS,3.10
