Geodetic Datums

A geodetic datum is a reference system used to measure and map locations on the Earth’s surface. It consists of a set of points and coordinates that help accurately define the shape and size of the Earth, providing a framework for positioning and navigation. Different datums serve various regions and purposes and can lead to discrepancies in measurements if not correctly aligned. They are essential for mapping, land surveying, and GPS technology, ensuring that locations are consistently and accurately represented across different applications.
