In geodetic engineering, what is the main focus of differential leveling?

Differential leveling is a critical technique in geodetic engineering, primarily aimed at determining the differences in elevation between points. This method involves establishing a benchmark or reference point and then measuring the elevation of other points relative to this reference. The main focus is to achieve highly accurate elevation determinations, which are essential for various applications, such as construction, land surveying, and establishing the topographic characteristics of an area.

While horizontal measurements, angle measurements, and land cover assessments are important elements in the broader scope of surveying and geodetic engineering, they are not the primary focus of differential leveling. This technique specifically addresses vertical relationships and height differences, making it indispensable for tasks that require precision in elevation data.
