Precise geoid determination over Sweden using the Stokes-Helmert method and improved topographic corrections
Nahavandchi, Hossein; Sjöberg, Lars Erik (Peer reviewed; Journal article, 2001)Four different implementations of Stokes's formula are employed for the estimation of geoid heights over Sweden: the Vincent and Marsh (1974) model with the high-degree reference gravity field but no kernel modifications; ... -
Two different views of topographical and downward-continuation corrections in the Stokes-Helmert approach to geoid computation
Nahavandchi, Hossein; Sjöberg, Lars Erik (Peer reviewed; Journal article, 2001)Two different methods to handle the topographical and downward-continuation corrections in Stokes' formula are investigated. The first approach is to correct observed gravity anomalies for the the effect of topographic ...
