WebThe geoid is defined as the surface of the earth's gravity field, which is approximately the same as mean sea level. It is perpendicular to the direction of gravity pull. Since the mass of the earth is not uniform at all points, and the direction of gravity changes, the shape of the geoid is irregular. WebThe geoid is essentially the figure of the Earth abstracted from its topographic features. It is an idealized closed equilibrium surface that is formed by the surface of sea water. This is …

WebThe geoid is an equipotential surface of the Earth's gravity field that approximates global mean sea level. You can visualize the geoid as the surface of the ocean without effects such as weather, waves, and land.
