The scientific discipline that studies gathering, storing, and processing geographic information.
The scientific discipline that combines applied mathematics and earth sciences in order to measure and represent the Earth. It studies phenomena such as gravitational fields, polar motion, and tides.
The technique of determining the terrestrial or three-dimensional position of points and the distances and angles between them.
Mathematics is the study of topics such as quantity, structure, space, and change. It involves the identification of patterns and formulating new conjectures based on them. Mathematicians strive to prove the truth or falsity of these conjectures. There are many fields of mathematics, some of which are widely used for practical applications.
