Everything about Geodesy
Science of measuring the shape, orientation, and gravity of Earth
Geodesy or geodetics is the science of measuring and representing the geometry, gravity, and spatial orientation of Earth in temporally varying 3D space. It is called planetary geodesy when studying other astronomical bodies, such as planets or circumplanetary systems. Geodetic job titles include geodesist and geodetic surveyor. Wikipedia →
