Overview

Aarhus Workbench is a unique and comprehensive software package for processing, inversion, and visualization of geophysical and geological data. The package integrates all steps in the workflow from handling the raw data to the final visualization and interpretation of the inversion models.
The Aarhus Workbench package includes dedicated data processing modules for many geophysical data types and an integrated GIS platform. It uses the robust and fast inversion code AarhusInv.

  Other

• Run inversions on local Servers/PC from local desktop.

• Aarhus Cloud inversion - run high computational demanding inversions in the Cloud

 

Visualization and interpretation

Visualization, evaluation, and geological interpretation of the inversion results is done with the GIS interface, which is integrated with the processing tool and cross sections. Aarhus Workbench is fully compatible with ArcGIS formats (GeoTiff, Shape-files) and Surfer grid file format.

 

GIS themes

• Creation of geophysical theme maps, e.g. mean resistivity, elevation of geological interfaces, etc.

• Gridding of themes using Kriging or inverse distance interpolation, including semi-variogram analysis.

• Visualization of theme maps as colorized points or grid images.

• Quality check of inversion results with model quality too.

• Borehole locations with easy access to detailed borehole reports.

• External GIS themes in ArcGIS formats (GeoTiff, Shape-files).

 

Cross sections

• Section location by drawing directly in the GIS-map or based on survey flight lines.

• Resistivity models displayed as bars or interpolated filled sections, combined with depth of investigation (DOI) information.

• Boreholes as bars with easy access to detailed borehole reports.

• Digitization of layer interfaces for easy geological model building.

• Sections combined with intersections in a grid displayed as lines.

• Extended label options for resistivity bars and boreholes; e.g. projection distances, lithology etc.

Presentation

• 3D viewer with tools for cutting/planes and parameter thresholds

• PDF report tool - Create pdf templates and high resolution pdf reports with data and results.
