A computational scheme to model the geoid by the modified Stokes formula without gravity reductions
LE Sjöberg - Journal of geodesy, 2003 - Springer
In a modern application of Stokes' formula for geoid determination, regional terrestrial gravity
is combined with long-wavelength gravity information supplied by an Earth gravity model …

Spatial and spectral representations of the geoid-to-quasigeoid correction
In geodesy, the geoid and the quasigeoid are used as a reference surface for heights.
Despite some similarities between these two concepts, the differences between the geoid …

The rigorous determination of orthometric heights
The main problem of the rigorous definition of the orthometric height is the evaluation of the
mean value of the Earth's gravity acceleration along the plumbline within the topography. To …

A discussion on the approximations made in the practical implementation of the remove–compute–restore technique in regional geoid modelling
LE Sjöberg - Journal of Geodesy, 2005 - Springer
The remove-compute-restore (RCR) technique is the most well known method for regional
gravimetric geoid determination today. Its basic theory is the first-order approximation of …

Empirical comparison between stochastic and deterministic modifiers over the French Auvergne geoid computation test-bed
Since 2006, several different groups have computed geoid and/or quasigeoid (quasi/geoid)
models for the Auvergne test area in central France using various approaches. In this …

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 …
