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.
