The function of a transit in land surveying primarily focuses on measuring horizontal and vertical angles. This instrument utilizes precisely calibrated optics and graduated circles to allow surveyors to determine angles in both two-dimensional and three-dimensional spaces.

Understanding the role of a transit is crucial for accurate surveying. When setting up the transit, the surveyor uses leveling screws to ensure the instrument is perfectly horizontal. Then, through sighting along the line of sight, they can determine the angle relative to a baseline or another point. This capability is essential for creating accurate maps, establishing property boundaries, and guiding construction projects.

In comparison, marking corners of a property, calculating land area, or providing GPS coordinates represent tasks associated with different tools or methodologies. For example, property corners might be marked using stakes or monuments, while land area calculations typically involve more iterative methods leveraging multiple measurements. GPS technology relates to a different set of instruments altogether, offering geographical positioning rather than angle measurements. Therefore, the superior functionality attributed to the transit is its ability to provide precise angular measurements foundational for various surveying applications.
