Explanation
Geodesy is the science of accurately measuring and understanding three fundamental properties of the Earth. These properties are—Earth’s geometric shape, the Earth’s orientation in space, and the Earth’s gravitational field. Along with this, it also studies changes in the above properties over time. Thus, geodesy is the science related to the measurement of the Earth’s dimensions.
