Differential Leveling Simulator

Visualize elevation changes by adjusting backsight and foresight readings.

Elevation A (m)100.00
Backsight (BS) (m)1.50
Foresight (FS) (m)2.00

Results

HI=ElevA+BS=101.50 m\text{HI} = \text{Elev}_A + \text{BS} = 101.50 \text{ m}
ElevB=HI−FS=99.50 m\text{Elev}_B = \text{HI} - \text{FS} = 99.50 \text{ m}
