The Earth Gravitational Models (EGM) are a series of geopotential models of the Earth published by the National Geospatial-Intelligence Agency (NGA). They are used as the geoid reference in the World Geodetic System. The NGA provides the models in two formats: as the series of numerical coefficients to the spherical harmonics which define the ...
Coordinates: 2°N 76°E. 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 peninsula, it is the Earth 's largest gravity anomaly. [1][2] It forms a depression in the sea level covering an area of about 3 million km 2 (1.2 million sq mi), almost ...
With a legacy of more than 100 years, the Better Business Bureau (BBB) is the go-to watchdog for evaluating businesses and charities. The nonprofit organization maintains a massive database of ...
The geoid undulation (also known as geoid height or geoid anomaly), N, is the height of the geoid relative to a given ellipsoid of reference. N = h − H {\displaystyle N=h-H} The undulation is not standardized, as different countries use different mean sea levels as reference, but most commonly refers to the EGM96 geoid.
Along with prohibiting reviews written by non-humans, the FTC’s rule also forbids companies from paying for either positive or negative reviews to falsely boost or denigrate a product.

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).
