## Classification Of Surveying – Everything You Need To Know

Surveying is the art of determining the relative positions of points that are on, above, or beneath the earth’s surface using linear or angular measurements. In this article, let’s discuss the various classification of surveying. There are different classifications of surveying based on, Let’s discuss each of them in detail. 1) The accuracy of surveying […]

## 10 Important Types of levelling in surveying

Levelling is the art of determining the relative heights of various points on the surface of the earth. It is the branch of surveying that deals with the measurements in the vertical plane. According to the method adopted, levelling may be classified broadly into two types namely, Let’s discuss each of the types of levelling

What is Plane Table Surveying? Plane table surveying is a graphical method of surveying in which both the observations and plotting of stations are done simultaneously on a sheet placed on a plane table fitted with a tripod in the field. It is a simple and fast survey and is mostly suitable for preparing small-scale

## Levelling staff – Everything you need to know about

What is a levelling staff? A levelling staff is a straight, rectangular wooden or aluminum rod having graduations imprinted on them. The foot of the staff represents the reading zero and reading increases with an increase in height. It is used with a levelling instrument to determine the difference in height between the two points

## 5 Types of levels used in levelling

There are two main instruments used in the levelling process. They are a level and a levelling staff. Let’s learn about levels in detail. What is a level? A level is an instrument which is used to create a horizontal line of sight for observing staff readings. Commonly, a level consists of the following parts,

## Levelling in surveying – A Brief Outline

What is levelling in surveying? Levelling is a branch of surveying aimed at the determination of elevation of a given point with respect to some assumed datum or some standard reference. In simple words, it is nothing but the process of finding a height of an object or a point relative to another point on,

## Prismatic compass Vs Surveyor’s compass

There are two main types of compasses used in compass surveying. They are, Prismatic compass Surveyor’s compass 1.Prismatic compass This type of Compass is the most convenient, light, and simple instrument and is used for rough surveys where too much accuracy is not needed. This instrument can be either handheld or fitted with a tripod.

## Compass Surveying

What is compass surveying? Compass surveying is an important branch of surveying that is usually adopted in determining the position of an object using both linear and angular measurements. The linear measurement can be measured with the help of a chain or tape and the angular measurement can be measured with the help of a

## Types of chain used in surveying

Types of chain used in surveying Chain surveying is the type of surveying in which only linear measurements are made in the field. Chain surveying derives its name from the fact that the principal equipment used in this process is the chain. There are different types of chain used in surveying. They are, Metric chain

## Chain surveying | Principle of chain surveying | Procedure of chain surveying

Introduction Before getting into the chain surveying, let’s learn some basics of surveying. There are two major measurements in surveying, they are linear measurements and angular measurements. In surveying, linear distance can be measured by various following methods, Direct Distance Measurement (DDM) Optical Distance Measurement (ODM) Electromagnetic Distance Measurement (EDM) In the case of direct
