Geodesy is the study of the Earth's shape, orientation and gravity field, as well as changes in these properties with time. With modern space-based geodetic techniques it is possible to measure positions and deformation of the Earth's surface with millimetre precision, and to define a precise global reference framework in which to make those measurements. Methods include space- and ground-based gravity surveying, GPS and Interfereometric Synthetic Aperture Radar (InSAR). These techniques allow us to better understand the Earth's internal properties and dynamic processes including active tectonics, Earth tides, glacial isostatic adjustment, the earthquake cycle and volcanism.
