Interactive Geophysical Modeling

IGMAS+ assists in integrated processing and three-dimensional (3D) interactive modeling of gravity and magnetic fields, yielding improved geological interpretation. IGMAS+ 3D models are constructed using triangulated polyhedra to which constant density and/or induced and remanent susceptibility are assigned. In the background a voxel cube is automatically defined allowing for arbitrary density or susceptibility distributions.

WYSIWYG – Interactive modifications of model parameters (geometry, density, and susceptibility), access to the numerical modeling process and direct visualization of both calculated and measured fields of gravity and magnetic enable the interpreter to design the model as realistically as possible.


IGMAS uses triangulated polyhedrons to model areas of constant physical parameters. The exact solution of the gravity potential is provided for the triangle model and – if wanted – also for the voxel grid, allowing for flexibel parameter distribution.
