Theodolite - SS2 Agriculture Lesson Note

A theodolite is a more advanced surveying instrument used for measuring horizontal and vertical angles with high accuracy.

It consists of a telescope mounted on a tripod, with precise mechanisms for rotation in both horizontal (azimuth) and vertical (altitude) planes.

Surveyors use theodolites to measure angles between reference points, which are crucial for determining distances and creating detailed survey maps.

Some theodolites also come with electronic distance measurement (EDM) capabilities for more comprehensive surveying.
