IGMAS+

IGMAS is an interactive, graphical modeling system for the 3D interpretation of potential field data from gravity and magnetics. The software offer full tensor gravity and can deal with all magnetic components.

Key Features

Easy 3D modeling of complex 3D structures
Intuitive User Interface for interactive modeling
Save time through advanced and highly optimized algorithms
Simultaneous 2D/3D model interaction and visualization
Joint inversion of potential field data
Combine different fields for optimal modeling output
Usage of voxel models in combination with IGMAS triangulated model geometries
use your own scripting engine for "remote controling" IGMAS

Geometry

The basic geometric element of the model is a triangulated surface, that separates two areas of different physical parameters. Any triangulated surface can be built in three different ways:

Through the import of gridded surfaces
Through the import of externally triangulated surfaces
An internal triangulation can be used to build a 3D geometry between several vertical, parallel sections

Algorithm

IGMAS uses triangulated polyhedrons to approximate areas of constant physical parameters within the Earth's crust and mantle. The Algorithm enables the calculation of

geoidal undulations
gravity components
all gradients (Full Tensor Gravity)
as well as remanent and induced magnetic field components with gradients

in one program step.

Hybrid Modelling

IGMAS now automatically calculates a re-sampled voxel model from a given triangulated polyhedron topology. With this Voxel Model complex distribution of physical parameters like density and susceptibility inside the solid polyhedrons can be defined. This gives the possibility of modelling complex physical parameter functions and the parallel calculation of FTG and magnetic fields from the polyhedron and voxel model.
