Definition of Geoid. Meaning of Geoid. Synonyms of Geoid

- The geoid (/ˈdʒiː.ɔɪd/ JEE-oyd) is the shape that the ocean surface would take under the influence of the gravity of Earth, including gravitational attraction...
- authors, such as the United States Census Bureau, use the abbreviation "GEOID" as a synonym for geocode. Geocodes are mainly used (in general as an atomic...
- The Indian Ocean Geoid Low (IOGL) is a gravity anomaly in the Indian Ocean. A circular region in the Earth's geoid, situated just south of the Indian...
- anomalies, defines the geoid of the Earth, which approximates the local mean sea level for locations in the open ocean. The geoid includes a significant...
- and gravimetric geoids. By matching the relative astro-geodetic geoids of the selected datums with an earth-centered gravimetric geoid, the selected datums...
- separation between the geoid and the reference ellipsoid is called the undulation of the geoid, symbol N {\displaystyle N} . The geoid, or mathematical mean...
- between the two, referred to as geoid undulations, geoid heights, or geoid separations, will be irregular as well. The geoid is a surface along which the...
- and longitude. In the first step the physical surface is modeled by the geoid, a surface which approximates the mean sea level over the oceans and its...
- the study of Earth's gravitational field is called physical geodesy. The geoid essentially is the figure of Earth abstracted from its topographical features...
- heights are zero is called the quasi-geoid (or quasigeoid), a representation of mean sea level similar to the geoid and close to it, but lacking the physical...
