What is chaining or taping?

Answer 1

Taping & Chaining

The measurement of distance with the help of chain or tape is known as chaining. The measurement of distance with the help of tape is known as taping. Chaining and taping are the methods of land surveying in which only linear measurements are made. Chain surveying requires the aid of chain, tapes and ranging rods. In chaining, the area to be surveyed is divided into an outline and this framework is comprised of triangles. Metallic tapes are widely used in surveying. A metallic tape is made of varnished strip of waterproof line, and the tape is entwined with small wires of brass and copper.

Measuring methods in Taping and Chaining

Measuring chain also known as surveyor chain is mainly used to calculate linear distances. With the help of surveyor chain distances between points are calculated accurately when global satellites to map distances from space were not in their role. To make measurements with chains, keep tallying tags in the chain and then divide it into 10 equal lengths as the first step in chaining. Next step is to shoot a line from the point of origin to the first visible object by detecting it with the aid of circumferentor. Make both chainmen to stand nearby. Pull the chain to its full length by sending the fore chainman towards the object. A marking should be made at the fore chainman's position. And then everyone is advanced towards the object to be detected keeping the chain tight.

Chain or Tape Surveying and its objectives

Chain or Tape surveying is the simplest form of detail surveying. With the help of tape method the lengths of lines marked on the field can be calculated and from ties in these lines details are collected. Investigating the area by walking around the area to be surveyed, help to locate apt stations and perfect chain lines essential for surveying. Methods are there to detect obstacles. Well formed linked triangles or braced quadrilaterals are created with the help of selected stations.Measuring the distance between points with the help of chain or any other similar tools to record the distance for the purpose of surveying is the basic idea in chain surveying. There are some features that cannot be seen in the line of measurement, in such cases we can select the location of points to be surveyed in a number of ways like using tie lines, offsets, and if using an angle measuring instrument, bearing and distance or juncture. Tie lines and offsets are commonly used in chain type of surveying , in that offset is most famous.
