WebFeb 4, 2024 · Some of the advantages of tacheometric surveying can be listed as follows: 1. The speed of such a survey is rapid. 2. The process eliminates the use of tapes and … 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.
