The local modeling of the gravity field has always been a theoretical challenge for geodesy, particularly at wavelengths comparable with the data window. Several solutions have been proposed all of which are known to leave long wavelength errors in the geoid. The current belief on the origin of this error is criticized.

Abstract

The local modeling of the gravity field has always been a theoretical challenge for geodesy, particularly at wavelengths comparable with the data window. Several solutions have been proposed all of which are known to leave long wavelength errors in the geoid. The current belief on the origin of this error is criticized. A new proposal, namely the use of the Slepian basis to overcome this difficulty, is illustrated in general terms.
