African Geodetic Reference Frame
The African Geodetic Reference Frame (AFREF) is a project designed to unify the many geodetic reference frames of Africa using data from a network of permanent Global Navigation Satellite Systems (GNSS) stations as the primary data source for the implementation of a uniform reference frame.

Angular momentum
In physics, angular momentum (rarely, moment of momentum or rotational momentum) is the rotational equivalent of linear momentum.

Cartesian coordinate system
A Cartesian coordinate system is a coordinate system that specifies each point uniquely in a plane by a pair of numerical coordinates, which are the signed distances to the point from two fixed perpendicular directed lines, measured in the same unit of length.

Cartography
Cartography (from Greek χάρτης chartēs, "papyrus, sheet of paper, map"; and γράφειν graphein, "write") is the study and practice of making maps.

Continental drift
Continental drift is the movement of the Earth's continents relative to each other, thus appearing to "drift" across the ocean bed.

Coordinate system
In geometry, a coordinate system is a system which uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements on a manifold such as Euclidean space.
