What defines a geodetic survey?

A geodetic survey is characterized by its consideration of the curvature of the Earth. This approach is essential for determining large-scale land measurements and positions with precision over extensive areas. Unlike plane surveys, which assume the Earth is flat and are suitable for smaller regions, geodetic surveys account for the Earth's shape, allowing for accurate measurement of distances and angles on a curved surface.

By integrating the Earth's curvature into its analysis, a geodetic survey can provide results that are valid across vast distances, making it crucial for national boundary determination, satellite positioning, and large-scale mapping projects. The process involves complex mathematical calculations and adjustments that account for the Earth's geoid and ellipsoidal shape.

The other choices do not encapsulate the essence of what a geodetic survey is about. While property ownership relates more to cadastral surveys, and digital mapping may be utilized in various types of surveys, they do not specifically address the fundamental aspect of curvature consideration that defines geodetic surveys. Additionally, surveys restricted to small areas typically do not require the advanced techniques associated with geodetic methodologies.
