Trigonometric Levelling & Tacheometry
Tacheometry, Instrument Used In Tacheometry – Tacheometer, Stadia Rod. Different Systems of Tacheometric Measurement- Stadia System (Fixed hair system, Movable hair system), Tangential System, Subtense Bar System, Theory of Tacheometer, Distance and Elevation Through Tacheometer- When a Staff Is Vertical, & When a Staff Is Perpendicular to Line of Sight.
