Which Situation Tacheometry Is Used?

Tachometry is used for preparation of topographic map where both horizontal and vertical distances are required to be measured; survey work in difficult terrain where direct methods of measurements are inconvenient; reconnaissance survey for highways and railways etc; Establishment of secondary control points.

What are the uses of Tacheometry?

The primary objective of this tacheometric surveying is to prepare contoured maps or plans requiring both the horizontal as well as vertical control. On surveys of higher accuracy, it provides a check on distances measured with the tape.

Which method of Tacheometry is most common in use?

As in the field of tacheometric surveying 'Stadia Method' is the most widely used procedure so we will discuss the principle behind it. The stadia method follows the principle that in similar isosceles triangles the ratio of the perpendicular to the base is constant.
