Understand the principles of levelling, types of levelling such as differential levelling and trigonometric levelling, and the procedures involved in determining elevations and creating level surfaces.
Levelling Techniques 1. What is Levelling? Levelling is a surveying method used to determine the height of a point relative to a known point or benchmark. It helps in creating accurate topographic maps, determining elevations, and monitoring changes in elevation over time. 2. Types of Levelling Techniques: a. Differential Levelling: - Involves measuring the difference in elevation between two po...…
