Theodolite Traversing in Survey and Procedure and Angle mesurements

Definition of Theodolite:




An optical instrument consisting of a small mounted telescope rotatable in horizontal and vertical planes, used to measure angles in surveying, meteorology, and navigation.


How to operate:

A theodolite is mounted on its tripod head by means of a forced centering plate containing four thumbscrews three for rapid levelling. Before use, a theodolite must be precisely placed vertical above the point to be measured using a plumb bob, optical plummet or laser plummet. The instrument is then set level using levelling footscrews and circular and more precise tubular spirit bubbles.
