Geoid Height and Deflections of the Vertical Models - National Geospatial Data Asset (NGDA) Geoid Models
In Gauss' words, the geoid is "the mathematical figure of the Earth". This figure is an equipotential surface coincident with the idealized mean sea surface. The geoid can be computed from the geodetic boundary value problems that use gravity data as its boundary value. A geoid model computed using gravity data is …
