Types Of Compass Pro Civil Engineer Astro compass; following are the compass types used for surveying. prismatic compass ; surveyor’s compass; level compass; a brief description of these types is given below. magnetic compass. the magnetic compass is a compass having a magnetized needle in line with the magnetic poles of the earth. fig 1: magnetic compass. By admin april 15, 2024. the types of compass that are used commonly are: (i) prismatic compass; and (ii) surveyor compass. the essential parts of both type are: (i) a magnetic needle, (ii) a graduated circle, (iii) a line of sight, and. (iv) a box to house them. there are some differences in the essential parts of the two type of compass.
Types Of Compass Surveying Principle of compass surveying. compass surveying relies on a technique called traversing, which uses a network of interconnected lines. the distances between the lines are measured using a chain or tape, and the magnetic bearings of the lines are measured using a surveyor compass. the creation of a network of triangles is not necessary for. Compass surveying is the branch of surveying in which the position of an object is located using angular measurements determined by a compass and linear measurements using a chain or tape. compass surveying is used in following circumstances: if the surveying area is large, chain surveying is not adopted for surveying rather compass surveying. In this chapter construction of different types of compasses, the system of noting bearings of the lines, some problems associated with measurement with compass are explained and then field work involved in compass survey is presented. 3.1 types of compass. 3.2 method of using a compass. 3.3 bearing. 3.4 whole circle bearing and reduced bearing. Here are some of the advantages of compass surveying: portability: compasses are relatively small and lightweight, making them easy to transport. this makes them ideal for surveying in remote areas or where access is limited. accuracy: compasses can be used to measure directions with a high degree of accuracy.

The survey points are connected as a series of lines. it is measured by the magnetic bearing of the compass instrument. the angle between the lines is measured, and the chain measures the length. it is known as the compass traversing. compass traversing computed in two ways such as open traverse and closed traverse. Prismatic compass: this type of compass has a built in magnifying lens, which makes it easier to read the compass card. prismatic compasses are often used by surveyors and other professionals who need to take accurate bearings. baseplate compass: this type of compass has a flat base, which allows it to be used with a map. baseplate compasses.
