Common Formulas
Elevation Difference
ΔH = BS - FS
Where: ΔH = Change in elevation, BS = Backsight, FS = Foresight
Slope Calculation
Slope (%) = (Rise / Run) × 100
Where: Rise = Vertical distance, Run = Horizontal distance
Practice Problems
Problem 1: Elevation Difference
Calculate the elevation difference between two points given:
- Backsight reading: 1.456m
- Foresight reading: 2.134m
Problem 2: Slope Analysis
Calculate the slope percentage between two points:
- Horizontal distance: 50m
- Vertical rise: 3m
