Geodesy — (pronEng|dʒiːˈɒdɪsi [OED] ), 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… … Wikipedia
Bessel ellipsoid — The Bessel ellipsoid (or Bessel 1841) is an important reference ellipsoid of geodesy. It is currently used by several national surveys of Europe and on other continents, but will be replaced in the next decades by modern ellipsoids of satellite… … Wikipedia
Earth ellipsoid — The Earth ellipsoid especially the mean Earth ellipsoid is the mathematical figure of the Earth which is used as a reference frame for computations in geodesy, astronomy and the geosciences.It is a ellipsoid of rotation, whose short (polar) axis… … Wikipedia
Hayford ellipsoid — The Hayford ellipsoid is a geodetic reference ellipsoid, named after the US geodesist John Fillmore Hayford (1868 1925), which was introduced in 1910. The Hayford ellipsoid was also referred to as the International ellipsoid 1924 after it had… … Wikipedia

Physical geodesy — [ NOAA)] Physical geodesy is the study of the physical properties of the gravity field of the Earth, the geopotential, with a view to their application in geodesy.Measurement procedureTraditional geodetic instruments such as theodolites rely on… … Wikipedia
Reference ellipsoid — In geodesy, a reference ellipsoid is a mathematically defined surface that approximates the geoid, the truer figure of the Earth, or other planetary body.Because of their relative simplicity, reference ellipsoids are used as a preferred surface… … Wikipedia
Undulation of the geoid — is a somewhat old fashioned name for the separation N between the geoid and the reference ellipsoid of the Earth.Because geophysical heights H above sea level refer to the geoid, but GPS positioning provides in a direct geometric fashion heights… … Wikipedia

History of geodesy — See also the main article on Geodesy. Humanity has always been interested in the Earth. During very early times this interest was limited, naturally, to the immediate vicinity of home and residency, and the fact that we live on a near spherical… … Wikipedia
World Geodetic System — The World Geodetic System defines a reference frame for the earth, for use in geodesy and navigation. The latest revision is WGS 84 dating from 1984 (last revised in 2004), which will be valid up to about 2010.Earlier schemes included WGS 72, WGS … Wikipedia
