Tag: Theodolite Angle measurement

A number of the techniques discussed in Chapter 3 require the measurement of angles, to a greater or lesser degree of accuracy. Horizontal and vertical angles can be measured approximately using a compass and clinometer, respectively; for more accurate work, a theodolite or total station will be needed. This chapter explains in detail how angles are measured using these instruments.

It is a commonly used instrument for measuring horizontal and vertical angles. It is used for prolonging a line, levelling and even for measuring the distances indirectly (techeometry). Using verniers angles can be read accurately up to 20″. Precise theodolites are available which can read angles up to even 1″ accuracy. They use optical principle for more accurate instruments. Now a days electronic
