• His discoveries in theoretical geophysics, the "precise geoid solution" in particular, enable millimetre-to-centimetre accuracy in geoid computation, an-order-of-magnitude improvement from previous solutions.
• One can relate these heights through the geoid undulation concept to "ellipsoidal heights" (also known as "geodetic heights"), representing the height of a point above the reference ellipsoid.
• To measure the local variation of Earth's topography, geodesy employs an idealized Earth producing a shape called a geoid.
• It can be related to orthometric height above the geoid by subtraction of the geoid height.
• The geopotential surface called the geoid is one definition of the shape of the Earth.

• VDs are used in astrogeodetic levelling: as a vertical deflection describes the difference between the geoidal and ellipsoidal normal direction, it represents the horizontal spatial gradient of the geoid undulations of the geoid (i.e., the separation between geoid and reference ellipsoid).
• Pannotia formed by subduction of exterior oceans (a mechanism called extroversion) over a geoid low, whereas Pangaea formed by subduction of interior oceans (introversion) over a geoid high perhaps caused by superplumes and slab avalanche events.
• Heiskanen on gravimetric geoid determination, publishing his dissertation "The Continental Undulations of the Geoid" in 1934 on the determination of a global geoid model from only 4500 data points.
• The areoid is a planetary geoid that represents the gravitational and rotational equipotential figure of Mars, analogous to the concept of geoid ("sea level") on Earth.
• Geoid Glacier (...) is a glacier flowing south from the Thomas Heights, to the west of Ellipsoid Hill, into Blue Glacier, Victoria Land, Antarctica.

• The difference between the resulting quasi-geoid and the reference ellipsoid is called the height anomaly or quasi-geoid height.
• In general the true vertical at a point on the surface does not exactly coincide with either the normal to the reference ellipsoid or the normal to the geoid.
• The separation between the geoid and the reference ellipsoid is called the "undulation of the geoid", symbol [...].
