what is theodolite?
A theodolite is a precision instrument for measuring angles in the horizontal and vertical planes. Theodolites are mainly used for surveying applications, and have been adapted for specialized purposes in fields like metrology . A modern theodolite consists of a movable telescope mounted within two perpendicular axes — the horizontal or trunnion axis , and the vertical axis. When the telescope is pointed at a target object, the angle of each of these axes can be measured with great precision, typically to seconds of arc.
Very correct definition on clinometer!! While working myself with different survey instruments like Theodolites , alignment telescope , Sight level , Total Station for couple of decades its quite refreshing
