The Influence of Bathymetry on Regional Marine Geoid Modeling in Northern Europe
Journal of Marine Science and Engineering, 2022 Although Northern Europe has been the target area in many regionwide geoid determination studies, the research has been land-focused, neglecting bathymetry information. With new projects, such as the Baltic Sea Chart Datum 2000, the attention is shifting

Exploration of tectonic structures with GOCE in Africa and across-continents [PDF]
, 2015 The gravity anomaly field over the whole Earth obtained by the GOCE satellite is a revolutionary tool to reveal geologic information on a continental scale for the large areas where conventional gravity measurements have yet to be made.

GOCE quasigeoid performance for Norway
International Journal of Applied Earth Observation and Geoinformation, 2015 Abstract We have compared the EGM08/GOCE quasigeoid with the height anomalies of a precise GPS/levelling network in the south of Norway where the GOCE ground tracks are dense and the gravitational signal has been described as rough. It was found that the inclusion of the GOCE gravity potential can improve the quasigeoid fit with the GPS/levelling ...

Tuning a gravimetric quasigeoid to GPS-levelling by non-stationary least-squares collocation [PDF]
, 2010 This paper addresses implementation issues in order to apply non-stationary least-squares collocation (LSC) to a practical geodetic problem: fitting a gravimetric quasigeoid to discrete geometric quasigeoid heights at a local scale. This yields a surface

On the Applicability of Molodensky’s Concept of Heights in Planetary Sciences
Geosciences, 2018 Geometric heights, defined with respect to a geometric reference surface, are the most commonly used in planetary studies, but the use of physical heights defined with respect to an equipotential surface (typically the geoid) has been also acknowledged ...

Contributions to Geophysics and Geodesy, 2020 The paper presents local quasigeoid modelling in Slovakia using the finite volume method (FVM). FVM is used to solve numerically the fixed gravimetric boundary value problem (FGBVP) on a 3D unstructured mesh created above the real Earth's surface ...

Pot do novega modela geoida v Sloveniji ( = Towards a new geoid model of Slovenia) [PDF]
Geodetski Vestnik, 2017 The geoid model is a component of the national coordinate system. This paper presents the main concept and role of the geoid within geodesy and other geo-sciences.

Unification of New Zealand's local vertical datums: iterative gravimetric quasigeoid computations [PDF]
, 2009 New Zealand uses 13 separate local vertical datums (LVDs) based on normal-orthometric-corrected precise geodetic levelling from 12 different tide-gauges.

Earth and Space Science, Volume 11, Issue 12, December 2024.Abstract Satellite‐derived global digital elevation models (DEMs) are essential for providing the topographic information needed in a wide range of hydrological applications. However, their use is limited by spatial resolution and vertical bias due to sensor limitations in observing bare terrain.
