Introduction

This document describes the main features of the software ERTLab, produced by Geostudi Astier s.r.l. It is a software programmed to manage geophysical data, to design, processing, visualize, and analyse geoelectric data.

With ERTLab Studio it is possible to:

  • Design the electrodes geometry: ERTLab Studio manages any type of array configuration, also unconventional configuration (as loop around buildings);

  • Generate 2D/3D sequences for surface, cross-borehole or surface-to-borehole electrode setups;

  • Compute the forward model of resistivity and chargeability;

  • Compute sensitivity analysis;

  • Compute the optimized sequence for multichannel instruments;

  • Import ERT data from a variety of sources;

  • Compute a pre-processing of the measurements through advanced features such as statistical analysis and filtering;

  • Create a custom mesh: it is possible to choose the dimension, the cells size, the boundary conditions, and there is the possibility to import a topography file and to insert stratigraphic layers;

  • Set starting model with a lot of customization options;

  • Compute data inversion;

  • Compute operation between file (useful in case of time-lapse survey);

  • Manages 4D projects.

Licenses

The software has different license levels:

  • Basic Level of Licence: ViewLab 3D works as a viewer and integrates ERT data and models in a single 3D graphical area. In the 3D visualization mode it is possible to visualize data through the insertion of custom sections, volumes, surface, and to integrate them with images, three-dimensional graphic objects, and DXF files.

  • Advanced Level of Licence: ERTLab Studio: works as a resistivity/chargeability/IP inversion software, managing every phase of an ERT survey, from the survey design to the pre-processing and inversion of collected data including forward models. All the Basic Level licence functions are included.

  • Graphic Pack: This is an add-on to enable the following features:

  • 4D: This is an add-on for ERTLab Studio only, to enable the Timelapse 4D Project.
