Geodesy

Geodesy or geodetics^[1] is the science of measuring and representing the geometry, gravity, and spatial orientation of the Earth in temporally varying 3D. It is called planetary geodesy when studying other astronomical bodies, such as planets or circumplanetary systems.^[2] Geodesy is an earth science as well as a discipline of applied mathematics,^[3]^[4] and many consider the study of Earth's shape and gravity to be central to the science.^[5]^[6]

Geodynamical phenomena, including crustal motion, tides, and polar motion, can be studied by designing global and national control networks, applying space geodesy and terrestrial geodetic techniques, and relying on datums and coordinate systems. Geodetic job titles include geodesist and geodetic surveyor.^[7]
