The company was established in 2015 as a private spin-off company from the HydroGeophysics Group at Aarhus University,

Aarhus GeoSoftware develops the processing, inversion and visualization software packages Workbench and SPIA for geophysical data made from electromagnetic and electrical instruments.

Professional software solutions for processing, inversion and visualization of geophysical data.

Res3DInv - DC/IP processing and inversion software

Res3DInv is a full featured 3D inversion software for ERT (DC) and IP data. The software offers a simple workflow from data import to inversion and visualization, while still offering full control over inversion parameters for advanced users. The software is highly optimized for speed so that small and medium sized surveys can easily be handled on modern consumer PCs, allowing initial in-field inversion for optimization of surveying efficiency.

The software is very flexible and can handle nearly every imaginable survey configuration, including topography, borehole and subsurface electrodes, spatially extended electrodes, arbitrary electrode locations, electrodes on and in water bodies and streamed electrode configurations.

The software supports visualization of vertical and horizontal resistivity sections, as well as export of data to Aarhus Workbench and to 3D visualization software such as ParaView, Slicer-Dicer, Voxler etc.

  • Inversion of ERT DC and IP data for resistivity/conductivity and chargeability.
  • Inversion of true 3D datasets as well as datasets combined from 2D survey lines.
  • Supports all common electrode configurations as well as arbitrary electrode configurations, borehole, subsurface and spatially extended electrodes.
  • Supports smooth and sharp inversions.
  • Removal of bad data points based on dataset- and inversion statistics.
  • Possibility to incorporate known geophysical information to guide and constrain inversion.
  • Easy visualization of horizontal and vertical sections or export to 3D visualization software.
