GG3D v6.0 Package

GG3D v6.0 is a program library for carrying out forward modelling and inversion of surface, borehole, and airborne gravity gradiometry data in 3D.

Highlights of GG3D v6.0

Many advancements have been made since the previous version of this coding package. Highlights of GG3D v6.0 include:

  • the ability to forward model and invert surface, borehole, and airborne gravity gradiometry data in 3D
  • the data can be full-tensor gradiometer (FTG) or the raw components of the Falcon or VK1 systems.
  • sensitivity weighting so that targets recovered through inversion are placed at the correct depth
  • the ability to recover compact and/or blocky models using sparse norms, in additional to smooth models using a standard least-squares approach
  • implementing wavelet compression to reduce the storage cost of the sensitivity matrix and allow the user to solve larger problems

Sponsorship

The current improvements have been funded by the GIFtools Consortium which included “Potential fields and software for advanced inversion” (2012-2020) sponsored by Teck, Glencore, BHP Billiton, Vale, Cameco, Barrick, Rio Tinto, and Anglo American.
