Sudan is characterized by vast area with flat terrains in most of the country's regions and therefore the existence of a high-resolution geoid model is considered very important …
This study emphasizes that the harmonic downward continuation of an external representation of the Earth's gravity potential to sea level through the topographic masses …

A new gravimetric geoid model, USGG2009 (see Abbreviations), has been developed for the United States and its territories including the Conterminous US (CONUS), Alaska …
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 …
Helmert's first and second method of condensation are reviewed and generalized in two respects: First, the point at which the effects of topographical and condensation masses are …
We analyse spatial and spectral characteristics of various refined gravity data used for modelling and gravimetric interpretation of the crust–mantle interface and the mantle …
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 …
