What is "Geodetic Surveying"?

Geodetic surveying is a branch of surveying that takes into account the Earth's size and shape, specifically its curvature, when determining positions on the Earth's surface. This type of surveying employs spherical geometry to accurately measure large distances and angles over the surface of the Earth. It is essential for mapping, navigation, and understanding the overall geometry of the Earth, especially for large-scale projects that span significant distances where the curvature cannot be ignored.

The emphasis on spherical geometry distinguishes geodetic surveying from other types of surveying that work on a smaller scale, where the Earth's curvature may not have a significant impact on measurements. By utilizing techniques that account for the Earth's three-dimensional shape, geodetic surveying provides highly accurate and reliable data that can be essential for various applications, such as satellite positioning, land development, and scientific research.
