Geoid or Quasi-Geoid? A Short Comparison
AbstractThis article is a short introduction to the debate on choosing the geoid and orthometric heights or the quasi-geoid and normal heights as the vertical coordinate system. It mainly compiles some more or less already known facts for comparing the two systems.

Airborne geoid determination [PDF]
Airborne geoid mapping techniques may provide the opportunity to improve the geoid over vast areas of the Earth, such as polar areas, tropical jungles and mountainous areas, and provide an accurate “seam-less” geoid model across most coastal regions. Determination of the geoid by airborne methods relies on the development of airborne gravimetry, which ...

The Mexican gravimetric geoid: xGGM23
The gravimetric geoid model xGGM23 was computed at the University of New Brunswick, Canada, with the aim to update the national geoid for Mexico, as well as to contribute to the construction of the regional geoid for North and Central America ...

The determination of the land geoid and the marine geoid involves different data sets and calculation strategies. It is a hot issue at present to construct the unified land–ocean quasi-geoid by fusing multi-source data in coastal areas, which is of great
