Geodetic North refers to the direction towards the North Pole as defined by the Earth's geometric shape and gravitational field. It is used in geodesy, the science of measuring and understanding the Earth's geometric shape, orientation in space, and gravity field. Geodetic North is essential for accurate mapping and navigation. Unlike magnetic north, which is influenced by the Earth's magnetic field and can vary over time, geodetic north provides a stable reference point. This distinction is crucial for activities such as GPS navigation, surveying, and cartography, ensuring that locations are accurately represented on maps and in various applications.
