大地测量学是一门地球科学分支，专注于地球的测量及其引力场的研究。该学科还研究地壳运动、潮汐及极移等现象，并设计全球及国家控制网，使用空间与地面技术进行测量。
Geodesy
From Wikipedia, the free encyclopedia
Geodesy (pronounced /dʒiːˈɒdɪsi/[1]), also called geodetics, a branch of earth sciences, is the scientific discipline that deals with the measurement and representation of the Earth, including its gravitational field, in a three-dimensional time-varying space. Geodesists also study geodynamical phenomena such as crustal motion, tides, and polar motion. For this they design global and national control networks, using space and terrestrial techniques while relying on datums and coordinate systems.
