Surveying is a crucial branch of civil engineering as a result of it's the primary step in beginning a new civil engineering project. A student should rigorously study the basics of surveying techniques so as to know them. to start learning surveying, one should initial perceive what measurement is and why it's vital.

Surveying

Surveying is the process of determining the relative position of various features on, above, or beneath the earth's surface using direct or indirect measurements and then representing them on a sheet of paper known as a plan or map.

 

 

The technique of establishing points by predetermined angular and linear measurements is also included in surveying. The area and volume of a specific plot of land can be calculated using surveying plans, sections, and maps. A map depicts the horizontal projection of the surveyed area rather than the actual area. The vertical distance, on the other hand, can be represented more accurately by drawing sections.

Surveyors use a variety of tools to complete their work successfully and accurately, including total stations, GPS receivers, prisms, 3D scanners, radio communicators, digital levels, dumpy levels, and surveying software.

 

Surveying's Importance

Surveying knowledge is useful in many phases of engineering. Surveying is critical in any engineering project. Some of the fundamental importance of surveying are discussed further below.

1.       During the execution of a project of any size, the lines and points established by surveying are followed.

2.       Surveying is required for the measurement of land and the establishment of its boundaries.

3.       A project's economic and engineering feasibility cannot be properly determined without first conducting a survey.

4.       It is necessary to carry out hydrographic and oceanographic charting and mapping.

5.       Surveying is the process of creating a topographic map of the earth's land surface.

6.       The first requirement for surveying is to create a plan and a section of the area that will be covered by the project. The best possible alignment, amount of earthwork, and other necessary details, depending on the nature of the project, can be calculated from these prepared maps and sections.

7.       Surveying measurements are used in the planning and design of all Civil Engineering projects such as railways, highways, tunnelling, irrigation, dams, reservoirs, waterworks, sewerage works, airfields, ports, massive buildings, and so on.
