Besides the Earth's gravitational field, 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 Contents Definition History Geoid and reference ellipsoid Coordinate systems in space ... edit Definition Geodesy (from Greek lit. division of the Earth) is primarily concerned with positioning within the temporally varying gravity field. Somewhat obsolete nowadays, geodesy in the German speaking world is divided into "Higher Geodesy" ("Erdmessung" or "h¶here Geod¤sie"), which is concerned with measuring the Earth on the global scale, and "Practical Geodesy" or "Engineering Geodesy" ("Ingenieurgeod¤sie"), which is concerned with measuring specific parts or regions of the Earth, and which includes surveying The shape of the Earth is to a large extent the result of its rotation, which causes its equatorial bulge, and the competition of geological processes such as the collision of plates and of

Geodesy is the science which makes global positioning possible. Geodesy is literally the science of measuring and monitoring the size and shape of the Earth and the location of points on its surface. NOAA's National Geodetic Survey (NGS) is responsible for the development and maintenance of a national geodetic data system that is used for navigation, communication systems, and mapping and charting. The Global Positioning Tutorial is an overview of the history, essential elements, and modern methods of geodesy. The Roadmap to Resources complements the information in the tutorial, leading you to additional information and data resources from NOAA and other reliable resources. The National Science Teachers Association (NSTA) has included this online resource in its SciLinks database.

The Space Geodesy Group engages in studies involving the application of Very Long Baseline Interferometry (VLBI) and the Global Positioning System (GPS) to geodesy and geophysics. Geodesy is the science of measurement of the size, shape, rotation, and gravitational field of the Earth. The Space Geodesy Group specializes in acquiring, analyzing, and interpreting space-based geodetic measurements. A variety of processes can influence geodetic measurements over a range of spatial and temporal scales, including: tides of the solid Earth and the oceans; weather and climate, and atmospheric structure and dynamics; hydrology and continental water storage; mass fluctuations and motions of glaciers and ice complexes; ocean and atmospheric circulation; changes in sea level; crustal motion associated with plate tectonics, earthquakes, and volcanos;

IUGG XXI General Assembly Program Committee Introduction and Mission The International Union of Geodesy and Geophysics (IUGG), which was established in 1919, is dedicated to the scientific study of the Earth and the application of the knowledge gained by such studies to the needs of society, such as more rational use of mineral resources, reduction of the effects of natural hazards, and environmental protection. The Union's objectives are the promotion and coordination of physical, chemical, and mathematical studies of the Earth and its environment in space. These studies include the shape of the Earth, its gravitational and magnetic fields, the dynamics of the Earth as a whole and of its component parts, the Earth's internal structure, the hydrologic cycle including snow and ice, all aspects of the oceans, the atmosphere, the ionosphere, magnetopshere, and solar-terrestrial relations, and analogous problems associated with the Moon and other planets. The IUGG has supported collaborative international interdisciplinary research programmes such as the International Geophysical Year (1957-58), the Upper Mantle Project (1964-70), the Geodynamics Project (1972-79), the Global Atmospheric Research Programme (1970-80), and the International Lithosphere Programme (1981-90). A major achievement has been the creation, through the International Council of Scientific Unions (ICSU), of the World Data Center System, from which the data gathered during these major programmes are available to research workers everywhere.

The group carries a time-honored heritage in generating the state-of-the-art gravity fields for the Earth, which is continuing into the new era of the International Decade of Geopotential Research. The same is true with respect to gravity fields of terrestrial planets and satellites in our Solar System. These efforts are based on the ever-improving precision in tracking of satellites and spacecraft, and in the capability of modeling and computation for precise orbit determination (POD) using the workhorse software GEODYN. The latter effort is also an integral part of current and future space missions that rely on POD, including ocean radar altimetry, land/ice laser altimetry and lidars, and new time-variable gravity measurement missions. New research in time-variable gravity and geocenter motion, joining the continuing studies of Earth rotation and crustal loading and deformation, constitute the "global geophysical fluids" research efforts whose main goal is to understand the Earth's atmosphere-hydrosphere-solid Earth-core system, and the dynamic interactions thereof. These efforts are based on space geodetic observations, a major component of which is

Geodesy From Wikibooks, the open-content textbooks collection Jump to: navigation search This text is taken from chapter 1 of the public domain resource Geodesy for the Layman please turn into a Wikibook Please edit this module to improve it. See this module's talk page for discussion. What is geodesy ? Webster defines geodesy as "that branch of applied mathematics which determines by observation and measurement the exact positions of points and the figures and areas of large portions of the earth's surface, the shape and size of the earth, and the variations of terrestrial gravity." It is a specialized application of several familiar facets of basic mathematical and physical concepts. In practice, geodesy uses the principles of mathematics astronomy and physics , and applies them within the capabilities of modern engineering and technology. In the past, military geodesy was largely involved with the practical aspect of the determination of exact positions of points on the earth's surface for mapping or artillery control purposes. The determination of the precise size and shape of the earth had a purely scientific role. Modern requirements are for answers to problems in satellite tracking , global navigation and defensive missile operations.
