Geometric geodesy

Geometric geodesy is the branch of Earth science focused on measuring and understanding the planet's shape and size using precise geometric methods. It involves determining the exact positions of points on Earth's surface and modeling its geometry as an ellipsoid, accounting for variations like mountains and valleys. By using tools such as satellites, GPS, and ground surveys, geometric geodesy provides accurate reference systems essential for mapping, navigation, and Earth monitoring. It helps us understand Earth's surface features and supports various scientific, engineering, and practical applications worldwide.
