Overview

Land survey determines the relative position of points below, above and on the earth’s surface. It is done by measuring the horizontal spaces between those points. It entails the method of creating points by predetermined linear and angular measurements. It uses a combination of mathematical, scientific and technical skills to create angles, distances and positions on the earth’s surface. Land survey services offer correct data that helps in decision-making process during different stages of a project.

What Tasks are Involved in Land Surveying?

Planning and Layout

Construction land surveying provides detailed information to civil engineers, including building footprints, drainage systems, and roadways. This data is essential for the best project layout.

Site Assessment

Site assessment survey allow civil engineers to assess possible construction sites and evaluate environmental factors, soil conditions and Topography that affect project feasibility.

Construction

During construction, accurate land surveying ensures that buildings are constructed according to the accepted plans. Professional land surveyors create markers and allow construction crews to retain accuracy.

Exactness:

Land surveyors make use of innovative measurement practices to get high level of exactness in deciding angles, distances and elevation. This accuracy helps in preventing expensive work and errors.

Possible Risks:

By doing comprehensive surveys, civil engineers can detect possible risks and dangers in the Construction place such as unbalanced soil conditions and environmental restrictions.

What are the Methods Employed for Land Surveying?

Plane Surveying:

Plane surveying is an important part of surveying and depends on measuring the area of plots or land. This type of surveying simplifies the surface of earth’s model by considering it as a planar surface, disregarding its spherical form. For its hands-on usability, plane surveying is used for architecture, engineering, military, commercial and navigation purposes.

Geodetic Surveying:

Geodetic surveying considers the shape of the earth, allowing curved lines be assessed and included in survey work. It allows wide areas to be correctly mapped. It also gives important data like point position, height above sea level and more accuracy and consistency in the survey results.

Total-Station Surveying:

Total station surveying is a must for land surveyors and engineers. Using technologies, such as optics, electronic distance meters and angle sensors, surveyors examines both horizontal and vertical angles within a matter of seconds. It is extraordinarily accurate and astonishingly portable, allowing users to carry it between work sites.

Tachometric Surveying:

Tachometric surveying encourages effectiveness within angular surveying. It removes the need for chaining, generating faster results.

GPS:

This technology has revolutionized the surveying field by producing better data collection correctness. GPS land surveying allows land surveyors to measure structures, terrains, land boundaries and distances with remarkable precision.
