Geodesy is the study and measurement of the Earth’s shape. It enables the calculation of positions and distances while taking into consideration the curvature of the Earth’s surface. Applications of geodesy include tracking changes in crustal motion, erosion, and post-glacial rebound. Examples of typical geodesic calculations include:
