Which statement best distinguishes plane surveying from geodetic surveying?
Correct answer: D. Plane surveying neglects earth curvature over the surveyed area
- A. Geodetic surveying does not require a reference datum
- B. Plane surveying uses only angular observations for control
- C. Geodetic surveying is limited to small construction sites
- D. Plane surveying neglects earth curvature over the surveyed area
Explanation
Plane surveying treats the earth's surface as approximately flat because the area is relatively small. Geodetic surveying considers earth curvature and is used for large areas or precise control networks.

About Surveying
Surveying covers measurement of distances, angles and elevations, traversing, levelling, contouring, plane table work, theodolites, total stations and basic photogrammetry. It includes error adjustment, coordinate calculations, area and volume determination, and the distinction between accuracy and precision, as well as between temporary and permanent adjustments.
