About Geodetic Systems
Geodetic system is the widely used technology wherein, it consists of a coordinate system along with the set of reference points used to locate places on earth. Geodetic systems are used in surveying by cartographers and satellite navigation systems.
Science of geodesy and geophysics that deal with information or Earth data pertaining to gravity, point positioning, datums, etc.
Geodetic datum (including coordinate datum, height datum, depth datum, gravimetry datum) and geodetic systems (including geodetic coordinate system, plane coordinate system, height system, gravimetry system) are the common foundations for every aspect of geomatics.
