Forward gravity field modelling requires high accurate determination of the topographic
potential on the surface of the Earth's ellipsoid. Since the topography is recently known with …

In the framework of the IAG African Geoid Project, an attempt towards a precise geoid model
for Africa is presented in this investigation. The available gravity data set suffers from …

Bathymetry data over lake areas are not included in the current and previous NGS (National
Geodetic Survey) geoid models. Lake surfaces are simply treated as land surfaces during …

In modern geodesy, the geoid computation is carried out using the so-called remove-restore
technique. In this technique, the effect of the topography and its isostatic compensation as …

The available gravity data set for Africa consists of land point gravity data as well as
shipborne and altimetry derived gravity anomalies data, but suffers from a lot of significant …

Some steps were taken recently for Hungary aiming at the determination of geoid heights
with a cm-accuracy. The present HGTUB98 gravimetric solution was based on terrestrial …

The aim of this paper is to investigate the effect of implementing the experimentally
determined GEMMA Moho depths (GOCE Exploitation for Moho Modeling and Applications) …

The primary task of the IAG Sub-Commission on Gravity and Geoid in Africa is the
development of the vertical reference surface (the geoid) for the entire African continent. For …

The paper presents an attempt to compute a geoid model for Africa in the framework of the
IAG African Geoid Project. The available gravity data set consists of land point gravity data …

The gravity database for the IAG African Geoid Project contains significantly large data gaps.
These large data gaps affect the interpolation precision of the reduced gravity anomalies …
