About this calculator
Angle of elevation: looking up from horizontal. Angle of depression: looking down. Same math: tan(angle) = vertical / horizontal. Used in surveying (height of building from across street), navigation (target ranging), and construction (slope grading). Always measure from horizontal eye level.
Frequently asked
Elevation: looking up. Depression: looking down. Math identical (alternate interior angles for horizontal observer).
