Which aspect is essential when surveying large parcels?

• A. Assessment of immediate surroundings
• B. Consideration of Earth's curvature
• C. Use of local landmarks
• D. Calculation of material quantities

Answer: (B)

Considering the Earth's curvature is essential when surveying large parcels because the Earth's spherical shape can affect measurements and calculations over long distances. For large parcels, especially those several square miles in size, the curvature can lead to significant discrepancies if not accounted for. Surveyors must apply precise methods, such as geodetic surveying techniques, that take this curvature into account to ensure accuracy in establishing property boundaries, elevations, and other critical measurements. In contrast, while assessment of immediate surroundings, use of local landmarks, and calculation of material quantities are all important factors in different surveying contexts, they do not directly address the challenges presented by large parcels. The local surroundings and landmarks may assist in orientation and reference but do not impact the geometric accuracy needed over extensive areas, where the curvature of the Earth becomes a critical factor. Additionally, material quantities pertain to construction and design phases rather than the surveying process itself.
