Geodesy
Tacheometry
Horizontal distances, height differences and stadia measurements.
Geodesy
Horizontal distance from slope
D = S cos v→GeodesyTacheometric height difference
h = S sin v + i − l→GeodesySlope distance from horizontal
S = D / cos v→GeodesyStadia distance
D = k(nᵤ − nₗ)→GeodesySurvey point X coordinate
X = X₀ + d cos α→GeodesySurvey point Y coordinate
Y = Y₀ + d sin α→GeodesyLongitudinal offset
l = S cos β→GeodesyTransverse offset
q = S sin β→GeodesyElevation interpolation
H = H₁ + (H₂ − H₁)l/L→
