Physical geodesy is the study of the physical properties of Earth's gravity and its potential field (the geopotential), with a view to their application in geodesy. Measurement procedure [ edit ]

A brief history of geodesy from NASA. [1]The history of geodesy (/dʒiːˈɒdɪsi/) began during antiquity and ultimately blossomed during the Age of Enlightenment.. Many early conceptions of the Earth held it to be flat, with the heavens being a physical dome spanning over it.
v. t. e. Physical geography (also known as physiography) is one of the three main branches of geography. [1][2][3][4][5] Physical geography is the branch of natural science which deals with the processes and patterns in the natural environment such as the atmosphere, hydrosphere, biosphere, and geosphere.
Veikko Aleksanteri Heiskanen. Veikko Aleksanteri Heiskanen ( V. A. Heiskanen; also spelled Weikko Aleksanteri (or W. A.) Heiskanen; 23 July 1895 – 23 October 1971) was a Finnish geodesist and geophysicist. [1] [2] He was known for his refinement of George Biddell Airy and John Henry Pratt 's theories of isostasy into his own, the Heiskanen ...
The World Geodetic System (WGS) is a standard used in cartography, geodesy, and satellite navigation including GPS. The current version, WGS 84, defines an Earth-centered, Earth-fixed coordinate system and a geodetic datum, and also describes the associated Earth Gravitational Model (EGM) and World Magnetic Model (WMM).
Earth science or geoscience includes all fields of natural science related to the planet Earth. [1] This is a branch of science dealing with the physical, chemical, and biological complex constitutions and synergistic linkages of Earth's four spheres: the biosphere, hydrosphere / cryosphere, atmosphere, and geosphere (or lithosphere). Earth ...
Geopotential spherical harmonic model. In geophysics and physical geodesy, a geopotential model is the theoretical analysis of measuring and calculating the effects of Earth 's gravitational field (the geopotential). The Earth is not exactly spherical, mainly because of its rotation around the polar axis that makes its shape slightly oblate.
