Calculate Point Elevations From Instrument Height For Inclined Sighting:

Calculation:

Designer/Checker:

Input:

Metric Units

Instrument Height (HI - ft or m)

Dist. center to forward lense (C - ft or m)

Stadia interval factor (K)

Point number (Pt1)

Upper stadia rod reading of first point (Pt1R2 - ft or m)

Lower stadia rod reading of first point (Pt1R1 - ft or m)

Angle of inclination to first point (Angle1 - deg)

Point number (Pt2)

Upper stadia rod reading of next point (Pt2R2 - ft or m)

Lower stadia rod reading of next point (Pt2R1 - ft or m)

Angle of inclination to next point (Angle2 - deg)

Output:

Point 1 Elev. =

Point 2 Elev. =
