Definition: Geodetic Survey
Geodetic surveys study Earth’s geodynamical phenomena (e.g., crustal motion, gravitational field) using a satellite-borne global positioning system (GPS) in conjunction with terrestrial base stations. Geodetic surveys measure three-dimensional changes in crustal motion at the mm-scale. Measurements are typically made over very large areas (1010 km2) spanning years.
