The primary use of a datum in surveying is to serve as a starting point or reference surface for measurement consistency. A datum provides a uniform basis from which all measurements can be taken, ensuring accuracy and repeatability in the surveying process. By establishing a common reference, surveyors can effectively compare and relate various measurements, which is essential for tasks such as defining property boundaries, creating accurate maps, and conducting topographical surveys.

This use of datum is critical in maintaining the integrity of surveying data, as it helps eliminate discrepancies that could arise from varying reference points. In contrast, the other options, while related to aspects of land surveying or property management, do not encapsulate the foundational role that datum plays in the measurement process. A datum isn’t primarily focused on legal disputes, software calculations, or land valuation, but rather on ensuring that measurements are accurate and consistent across the surveying discipline.
