FITTING OF A TRANSFORMATION GEOID MODEL TO THE GRAVIMETRIC-GEOMETRIC GEOID MODEL OF BENIN CITY
FUDMA JOURNAL OF SCIENCES, 2022 The application of the transformation geoid model in Benin City has necessitated its fitting to the existing gravimetric-geometric geoid model of the study area. The transformation geoid model was determined using the Kotsakis (2008) model for the transformation of global geoid heights to local geoidal undulations. To obtain its accuracy, the root mean

Topographic Effects in Geoid Determinations
Geosciences, 2018 Traditionally, geoid determination is applied by Stokes’ formula with gravity anomalies after removal of the attraction of the topography by a simple or refined Bouguer correction, and restoration of topography by the primary indirect topographic ...

Problems of the evolution of the figure and the earth's gravitational field [PDF]
E3S Web of Conferences, 2022 The relevance of geoid research involves examining a number of problems, the consideration of which reveals the evolution of the geoid. Measurements of the geoid help to understand the internal structure of our planet.

Airborne geoid determination [PDF]
Earth, Planets and Space, 2014 Airborne geoid mapping techniques may provide the opportunity to improve the geoid over vast areas of the Earth, such as polar areas, tropical jungles and mountainous areas, and provide an accurate “seam-less” geoid model across most coastal regions. Determination of the geoid by airborne methods relies on the development of airborne gravimetry, which ...
