1. Tacheometry

Tacheometry is a method that allows for the measurement of horizontal and vertical distances using angular observations with a tacheometer, proving to be more efficient than traditional chaining methods, especially in rough terrains. Key instruments include the tacheometer and levelling rod, while methods vary based on whether the line of sight is horizontal or inclined. Procedures for trigonometrical levelling and traverse computations are important for determining object heights and managing coordinate computations.
