Theodolite Traversing by Included Angle Method (Part - 1)

The theodolite traversing method is one of the basic traversing method used in older days. This method highlights the included angle acquiring method on the field. In this video the least count of the vernier theodolite is 20 sec. The distances of the traverse legs are measured with measuring tape and the bearing of line is taken with the help of compass app in mobile. The sum of total angles must be checked with the formula (2N - 4) x 90 and the error, if any, is equally distributed among all angles.
