Document Summary
Tacheometry is defined as the branch of surveying in which horizontal and vertical distances between stations are determined from instrumental observations. In this method, no a tape or a chain is used for measuring horizontal distances. The instrument which is used for tacheometric purposes, is known as a tacheometer. The accuracy of tacheometry distances is such that under favourable conditions, the error seldom exceeds 1 in. The primary object of tacheometry is the preparation of countered plans. It is considered to be rapid and accurate in rough country and has thus been widely used by engineers in location surveys for railways, canals, reservoirs, etc. Tacheometry provides more accuracy on distances measured with a tape or a chain. The following instruments are used : tacheometer. A tacheometer is essentially nothing more than a theodolite fitted with stadia hairs, is generally used for tacheometric surveying.
