The effect of anomalous global lateral topographic density on the geoid-to-quasigeoid separation
The geoid can be computed from the quasigeoid by applying the geoid-to-quasigeoid
separation. The geoid-to-quasigeoid separation is also needed for a vertical datum …

Effect of a high-resolution global crustal model on gravimetric geoid determination: a case study in a mountainous region
RA Abbak - Studia geophysica et geodaetica, 2020 - Springer
A precise gravimetric geoid model is determined by using Stokes formula assuming that
there is no topography above the geoid. Then, the geoid model is simply corrected by …
