Levelling Survey Unit – Description
This unit introduces students to the fundamental principles and practical techniques of levelling in surveying. Levelling is a key operation used to determine height differences between points on the Earth's surface. It plays a crucial role in construction, civil engineering, and topographic mapping.
The unit covers the theory behind levelling, types of levelling (such as differential, fly, and profile levelling), and the proper use of levelling instruments including the dumpy level, automatic level, and levelling staff. Students will gain hands-on experience in setting up and using equipment, recording field observations, calculating reduced levels using the height of collimation and rise and fall methods, and identifying common errors.
By the end of this unit, learners will be able to perform basic levelling tasks, interpret levelling data accurately, and understand the significance of levelling in real-world engineering and land surveying projects.
