Geodesy is the study of the:

• size and shape of the Earth
• measurement of the position and motion of points on the Earth's surface
• configuration and area of large portions of the Earth's surface.

Geodesy is a dynamic application of scientific methods in support of many professional, economic and scientific activities and functions, ranging from land titling to mineral exploration; from navigation, mapping and surveying to the use of remote sensing data for resource management; from the construction of dams and drains, to the interpretation of seismic disturbances.
