# MEANING OF CHAIN SURVEYING & ITS PRINCIPLES

MEANING OF CHAIN SURVEYING & ITS PRINCIPLES

Chain surveying is the method of surveying in that horizontal measurement and angle area taken in fieldwork. These types are of surveys main suitable for surveying small areas of land. It describes the boundaries of the plot, area of land, and other distances and angles on the field. In chain surveying, measurements are noted in separate book which is called “filed book”. The data of the survey includes – angle measurement, distance measurement, survey station, and base details, etc. These data in the filed book is used to draw the survey work on the paper by taking proper scale.

Principles Of Chain Surveying

The main principle of surveying is to divide the area of a survey into numbers of small survey areas by using triangles. Measure the length with tap and angle with a compass. The measurement is used to plot a survey drawing on paper. Since triangulation forms the principle of chain surveying, the chain survey is similarly sometimes called chain triangulation.

If the area to be surveyed is triangular and if the lengths and sequence of its 3 sides are recorded, the plan of the area can be easily drawn. However, if the area has more than three straight boundaries, for instance as in figure (a) it is no longer enough to measures the lengths of the sides completely.
