Geoid Determination

Geoid determination involves measuring Earth's gravitational field to define a smooth, mathematical surface that closely represents mean sea level across the globe, accounting for variations caused by Earth's density and rotation. This surface, called the geoid, serves as a reference for measuring elevation and understanding gravity-related phenomena. Scientists use satellite data, gravity measurements, and oceanography to model the geoid accurately. This information is crucial for accurate mapping, navigation, and understanding Earth's shape and gravity variations.
