Differentiate between plane and geodetic surveying? ?

Plane surveying is a type of surveying that assumes the Earth's surface is flat and uses a two-dimensional coordinate system to represent locations on the Earth's surface. It is typically used for small-scale surveys over relatively small areas.

Geodetic surveying, on the other hand, takes into account the curvature of the Earth and uses a three-dimensional coordinate system to represent locations on the Earth's surface. It is used for large-scale surveys over large areas and is more accurate than plane surveying due to its consideration of the Earth's curvature. Geodetic surveying is often used for projects such as mapping large areas, establishing control points for construction projects, and monitoring movements of the Earth's crust.
