Local Gravity Field Modeling

Abstract

In this report, an experiment is described wherein a local gravity field model was computed in mountainous terrain using digital terrain data, spherical harmonic coefficients, and local observations. The accuracies of free air gravity anomalies, deflections of the vertical, and geoid undulations computed are discussed. Keywords: Deflection of the Vertical; Digital terrain models/ Collocation; Geoid; Geoid; Geoid undulation; Geodesy; Gravity; Isostacy; Spherical harmonics.
