CST Level 1 Land Surveyor Certification Practice

Which equipment is specifically referred to as measuring vertical and horizontal angles?

1. Total Station

2. Surveying Level

3. Theodolite

4. Measuring Tape

The correct answer is: Theodolite

The equipment specifically referred to as measuring vertical and horizontal angles is the theodolite. A theodolite is an accurate instrument used in surveying for measuring angles in the horizontal and vertical planes. It features a rotating telescope that allows the surveyor to precisely sight and measure angular positions relative to a baseline or reference point. This capability makes the theodolite crucial for various surveying tasks, including establishing control points, conducting triangulation, and laying out construction projects. While total stations can also measure angles and distances and incorporate electronic elements for better functionality, the traditional and specific function of measuring angles aligns closely with the definition of a theodolite. In contrast, surveying levels are primarily designed for measuring differences in elevation, and measuring tapes are used for determining distance rather than angles. Thus, the theodolite is uniquely recognized for its role in angle measurement within the field of land surveying.
