General Description of the Course: Levelling Survey
Levelling Survey is a fundamental course in the field of land surveying and civil engineering. It introduces trainees to the principles, methods, and instruments used to determine the relative heights (elevations) of points on the earth's surface. The course emphasizes accurate measurement and data recording to ensure correct elevation profiles, which are essential for designing infrastructure such as roads, bridges, drainage systems, and buildings.
The course trains students to use levelling equipment such as the dumpy level, automatic level (auto level), levelling staff, and related accessories. Practical skills, including setting up instruments, taking readings, and performing arithmetic calculations, are core components of the training.
