Prediction of geoid undulations: Random forest versus classic interpolation techniques

Concurrency and Computation: Practice and Experience, 2022
AbstractLocal geoid determination studies are commonly carried out today to establish the relationship between the ellipsoidal height determined by satellite geodesy methods and the orthometric height found using geoid undulation . The aim of this study was to determine a local geoid using the kriging, local polynomial (LP), and inverse distance to a

Modelling geoid undulations with an artificial neural network

IJCNN'99. International Joint Conference on Neural Networks. Proceedings (Cat. No.99CH36339), 2003
Examines the use of a backpropagation neural network to model geoid undulations. Modelling of the Earth's gravity field, and in particular the separation between ellipsoid and geoid surface, is one of the fundamental problems in the field of geodesy.

Geoid undulation accuracy

IEEE Transactions on Geoscience and Remote Sensing, 1993
For use in oceanographic applications the geoid is ideally needed to a high accuracy and to a high resolution. In 1979 the cumulative geoid undulation error to spherical harmonic degree 20 was +or-1.4 m for the GEM10 potential coefficient model. Today the corresponding value has been reduced to +or-25 cm for GEM-T3 or +or-11 cm for the OSU91A model ...
