The vertical component(altitude)is measured in meters from the WGS84 EGM96 Geoid vertical datum.
The geoid height variation is under 110 m on Earth.

A geoid can be defined as an equi-potential surface of the earths gravitational field.
Presently WGS 84uses the 1996 Earth Gravitational Model(EGM96) geoid, revised in 2004.
The deviations of the EGM96 geoid from the WGS 84 reference ellipsoid range from about- 105 m to about +85 m.
Currently, WGS 84uses the Earth Gravitational Model 1996(EGM96) geoid, revised in 2004.
The geoid rises up to 70 m above the geodetic reference ellipsoid in an approximately circular area with a diameter of several hundred kilometers.
The north Atlantic is characterized by strong,large-scale anomalies of the gravity field and the geoid.
The geoid height can change abruptly due to earthquakes(such as the Sumatra-Andaman earthquake) or reduction in ice masses(such as Greenland).
WGS-84 currently uses the 1996 Earth Gravitational Model(EGM96) geoid, which was revised in 2004.
The local direction of gravity is normal to the geoid, and the angle between this direction and the normal to the ellipsoid is known as the deflection of the vertical.
In order to study the Earth and use geodesy today,researchers often refer to the ellipsoid, geoid, and datums.
The geoid might appear to be a theoretical concept of little practical value, particularly in the case of points on the land surface of the continents, but such is not the case.
The differences in elevation determined are therefore with respect to the equipotential andso very nearly with respect to the geoid.
It is true that modern methods of geodetic positioning(discussed below)have altered this approach, but the geoid remains an important concept with definite practical utility.
The value of the radius is completely dependent upon the latitude in the case of an ellipsoid model,and nearly so on the geoid.
Because the natural shape of the Earth( the Geoid) is not suitable, due to the complexity of mathematical calculations, so even in our computer age, can not do without errors.
Creation of geomorphologic and satellite data databases andmapping of West Antarctic region with aim to study the geoid topography.
This geoid defines the nominal sea level surface by means of a spherical harmonics series of degree 360(which provides about 100 km horizontal resolution).

For the investigation of postulated plumes, gravimetric, geoid and in particular seismological methods along with geochemical analyses of erupted lavas have proven especially useful.
Applying astronomical techniques, he measured the length of one degree of the meridian, and showed that the Earth's shape isdifferent from an ellipsoid of revolution(he coined the term geoid, which is still used today).
This geoid defines the nominal sea level surface by means of a spherical harmonics series of degree 360(which provides about 100 km latitudinal resolution near the Equator).

The models were used toinvestigate marine tectonic features such as geoid height variations across deep ocean trenches and fracture zones, lithospheric cooling and subsidence, and the isostatic compensation of seamount chains.[3].
