geodetic coordinate system

A geodetic coordinate system is a way to pinpoint locations on Earth's surface using a set of reference points. It typically employs latitude and longitude—imaginary lines running east-west and north-south—organized on a model of Earth's shape, called a geoid. This system allows precise positioning for navigation, mapping, and surveying, reflecting Earth's true shape rather than a simple sphere. It ensures consistency across different maps and technologies, enabling accurate location knowledge worldwide.
