Study Notes

Surveying: A Comprehensive Guide to Land Surveying

Surveying is the technique, profession, or science of making a measured drawing of a portion of the Earth's surface, called a land survey, for purposes of mapping, land boundaries, and construction. Surveying is used in the construction of roads, bridges, tunnels, dams, and buildings. It is also used in the exploration of land and water, and in the location of underground pipelines and cables. In the context of this article, we will focus on land surveying.

History of Surveying

The word "survey" has its origins in the Latin word "survey", which means "to look at, to view". The modern system of land surveying originated in Great Britain, and the first practical application of the principles of modern surveying was in the development of the metes and bounds system of land surveying.

Types of Surveying

There are two main types of surveying:

Engineering Surveying: This type of surveying is used to measure the land for the construction of various types of engineering projects, such as roads, bridges, tunnels, and buildings.
Geodetic Surveying: This type of surveying deals with the detection and determination of the shape of the Earth's surface and the measurement of the Earth's size and shape.

Land Surveying Process

Land surveying involves the following steps:

Establishing a Reference Point (Benchmark): This is the starting point of the survey.
Taking Angular Measurements: These measurements are used to determine the direction of the survey.
Taking Distance Measurements: These measurements are used to determine the distance between the reference point and the location being surveyed.
Recording the Survey Results: The survey results are recorded in a survey book, which contains a detailed description of the survey.
Analyzing the Survey Results: The survey results are analyzed to determine the boundaries of the land being surveyed.

Surveying Equipment

Surveying equipment includes:

Theodolite: A theodolite is an instrument used to measure horizontal and vertical angles.
Chain: A chain is used to measure distance.
Transit: A transit is an instrument used to measure horizontal and vertical angles.
Level: A level is used to measure the height of the surveyor from the ground to the instrument.
Surveyor's Tape: A surveyor's tape is used to measure small distances.

Surveying in Construction

Surveying plays a crucial role in construction projects. Before starting a construction project, a land surveyor is called to the site to determine the boundaries of the land. The surveyor uses surveying equipment to mark the corners and boundaries of the land. This information is then used by the construction team to build the project according to the specified dimensions.

Surveying in Mining

In mining, surveying is used to determine the location of underground reserves of minerals. This information is used by mining companies to plan and execute their operations. Surveying is also used to ensure that the mining operations are carried out within the legal boundaries of the land.

Surveying in Transportation

In transportation, surveying is used to plan and construct roads, bridges, tunnels, and other transportation infrastructure. Surveying is used to determine the topography of the land and to ensure that the infrastructure is built according to the specified specifications.

Surveying in Water Resources

In water resources, surveying is used to locate underground pipelines and cables. This information is used by utility companies to plan and maintain their infrastructure. Surveying is also used to determine the topography of the land to ensure that water resources projects are built according to the specified specifications.

Conclusion

Surveying is a crucial field that plays a vital role in various industries, including construction, mining, transportation, and water resources. It involves measuring the land for the purpose of mapping, land boundaries, and construction. The information gathered through surveying is used to plan and execute various projects accurately and efficiently.
