## What are the basic principles in surveying?

Two basic principles of surveying are: • Always work from whole to the part, and • To locate a new station by at least two measurements ( Linear or angular) from fixed reference points.

## What equipment is used for surveying?

The main pieces of surveying equipment in use around the world are the following: theodolite, measuring tape, total station, 3D scanners, GPS/GNSS, level and rod.

What is the first principle of surveying?

Explanation: The first principle of surveying is to work from whole to part. Before starting the actual survey measurements, the surveying is to work from around the area to fix the best positions of survey lines and survey stations.

### What are the principles and objectives of surveying?

To determine the relative position of any objects or points of the earth. To determine the distance and angle between different objects. To prepare a map or plan to represent an area on a horizontal plan. To develop methods through the knowledge of modern science and the technology and use them in the field.

### What is the second principle of surveying?

According to the second principle, the new stations should always be fixed by at least two measurements (linear or angular) from fixed reference points. Linear measurements refer to horizontal distances measured by chain or tape.

What are the principles of surveying what are the different types of chain and explain?

Principle of Chain Surveying: Since triangulation forms the principle of chain surveying, the chain survey is also sometimes called as chain triangulation. If the area to be surveyed is triangular in shape and if the lengths and sequence of its three sides are recorded, the plan of the area can be easily drawn.

## Which equipment are used for measuring the base line?

Invar tape is used for the base line measurement.

## What are the principles of surveying in civil engineering?

What is Surveying? : 5 Principles of Surveying, Objectives & Uses of Surveying

• a. Working from Whole to Part.
• b. Location of Point by Measurement From Two Points of Reference.
• c. Consistency of Work.
• d. Independent Check.
• e. Accuracy Required.

What is the principle of levelling?

The principle of levelling is to obtain a horizontal line of sight at which the vertical distance of a point above or below this line of sight is found. The main purpose of balancing in the survey is: Find the heights of the given points in relation to the given data.

### What is the basic principle of chain surveying explain the importance of base line in chain surveying?

The principle of chain surveying is triangulation. This means that the area to survey is spilled into a number of small triangles which should be well-conditioned. In chain surveying, the side of the triangles are measured directly from the field by chain or tape, and no angular measurements are used.

### What is the principle of compass surveying?

Principle of Compass Surveying The Principle of Compass Survey is Traversing; which involves a series of connected lines the magnetic bearing of the lines are measured by prismatic compass and the distance (lengths) of the area measured by chain. Such survey does not require the formulation of a network of triangle.
