Geodesy is the ancient science of measuring the Earth. It is now considered to be a subdiscipline of cartography. One of the primary concerns of geodeticists is the coordinatization of the Earth. Geodesy has also studied the physical form of the earth, with a large number of societies in antiquity speculating over its form and physical shape.[1] In recent decades, advances in technology have led to a more consistent understanding, with increasing levels of accuracy.
