Pe***e also ask : What is EGM 2008?
Earth Gravitational Model 2008 (EGM2008) GeographicLib provides a utility GeoidEval (with source code) to evaluate the geoid height for the EGM84, EGM96, and EGM2008 Earth gravity models. Here is an online version of GeoidEval.
Pe***e also ask : What is the difference between EGM2008 and ellipsoid?
Mean sea level is a geoid surface of the ocean in rest, EGM2008 is a model approximation of the geoid. An ellipsoid is the first order approximation of the shape of the Earth. Elevations are usually expresssed relative to the geoid as spirit levels are used for measurements.
Pe***e also ask : What is the Earth gravitational model 2008 egm 2008?
EGM2008 is a spherical harmonic model of the Earth's gravitational potential, developed by a least squares of the ITG-GRACE03S gravitational model and its associated error covariance matrix, with the gravitational information obtained from a global set of area-mean free-air gravity anomalies defined on a 5 ...
