Local Gravity Field Modelling in Rugged Terrain Using Spherical Radial Basis Functions: Case Study for the Canadian Rocky Mountains
We analyze the performance of a least-squares approximation of the gravity field using Spherical Radial Basis Functions (SRBFs) in rugged mountains. The numerical experiment is conducted for the gravity distur...

Comparison of Regional and Global GRACE Gravity Field Models at High Latitudes
In this study we address the question of whether regional gravity field modeling techniques of GRACE data can offer improved resolution over traditional global spherical harmonic solutions. Earlier studies int...

Open AccessA data-driven approach to local gravity field modelling using spherical radial basis functions
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 gravi...

A data-adaptive design of a spherical basis function network for gravity field modelling
A data-adaptive strategy for the design of spherical basis function (SBF) networks is presented. The strategy comprises a data-driven selection of the SBFs prior to parameter estimation and an automatic select...

Local gravity field modelling with multi-pole wavelets
We propose an alternative approach to the application of spherical wavelet functions for local gravity field modelling from terrestrial, airborne and/or space-borne data. Instead of estimating the finest scale...
