WebSep 6, 2024 · A tacheometric surveying is a branch of surveying in which we find the horizontal and vertical position of point on earth surface with the help of tacheometer. In this type of surveying there is no need of chain or tape for distance measurement and separate level for the measurement of elevation. WebTriangles. 1. A chain of triangles is very rapid and economical when a narrow strip of terrain is to be surveyed. 2. Angles less than 30 o or more than 120 o are not permitted 3. For well-conditioned triangles, angles should not be less than 30 o or more than 120 o . Advantages of triangles: This is simple and rapid. Economical method.
Tacheometry is a system of rapid surveying, by which the horizontal and vertical positions of points on the earth's surface relative to one another are determined without using a chain or tape, or a separate levelling instrument. Instead of the pole formerly employed to mark a point, a staff similar to a level staff is used. This is marked with heights from the base or foot, and is graduated according to the form of tacheometer in use.
