Klees, R. (author), Tenzer, R. (author), Prutkin, I. (author), Wittwer, T. (author)We propose a methodology for local gravity field modelling from gravity data using spherical radial basis functions. The methodology comprises two steps: in step 1, gravity data (gravity anomalies and/or gravity disturbances) are used to estimate the disturbing potential using least-squares techniques. The latter is represented as a linear...journal article 2008
