Jackson, K. and Hart, L. (2026) The Status of the Gravimetric Geoid across Nigeria. International Journal of Geosciences, 17, 49-65. doi: 10.4236/ijg.2026.171004 .
The coordinate system used by GPS is WGS 84, which expresses altitudes as a "height above ellipsoid". Because this ellipsoid is a mathematical simplification, the height given by GPS does not ...
Abstract: The practicality of gravimetric methods for heighting depends on the reliability of the geoid model. This paper covers the evaluation of selected Global Geopotential Models (GGM) over the ...
