Absolute and relative gravimetry allow the determination of gravity acceleration, usually just called gravity, for specific positions as well as the detection of gravity changes with time at a given location. For high-accuracy demands, the geometrical position of a gravity point has to be defined very accurately, e.g. in geodynamic research projects, at a height along the vertical above a ground mark. Geodetic networks with local, regional or global extent can be surveyed to monitor short-term and long-term gravity variations.
