Title: Comparison of Geoids from Several Geopotential Coefficients in Spain
Abstract: In Spain several geoid determinations have been done from three spherical harmonic expansion models of degree and order 360, namely, IFE88E2, OSU89B and OSU91A. Comparisons to a geoid solution computed by using least-squares collocation from gravity anomalies with the additional use of topographic data have been made in Central Spain in order to study the accuracy of these geoid determinations. Comparisons between observed and geopotential model implied gravity anomalies show that the IFE88E2 model is more adequate for this area. Statistics concerning the mean and standard deviation of differences are presented.
