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 and Earth's rotation, if other …

The geoid is an imaginary sea level surface that undulates (has a wavy surface) over all of the earth; it isn’t just for the oceanic areas, it also extends through the land masses.

Geoid, model of Earth’s size and shape that coincides with mean sea level over the oceans and continues in continental areas as an imaginary sea-level surface.

This irregular shape is called "the geoid," a surface which defines zero elevation. Using complex math and gravity readings on land, surveyors extend this imaginary line through the continents.

The meaning of GEOID is the surface within or around the earth that is everywhere normal to the direction of gravity and coincides with mean sea level in the oceans.

The geoid is the surface of an ideal global ocean in the absence of tides and currents, shaped only by gravity. The colours in the image represent deviations in height from an ideal geoid.

The geoid is a mathematical model of the Earth in which the geoid surface coincides exactly with the average elevation of the surface of the planet’s oceans. This model surface is extended …

The geoid is defined as an equipotential surface of the Earth's gravity field that corresponds to the undisturbed global sea level, serving as a height reference surface for measuring orthometric …

Apr 11, 2023 · Geoid is an imaginary surface that is used as a reference level for measuring elevations on the Earth’s surface. It is used in physical geography and geodesy to determine …

The geoid is often expressed as a geoid undulation or geoidal height above a given reference ellipsoid, which is a slightly flattened sphere whose equatorial bulge is caused by the planet's …
