IRIS Instruments Electre Pro 2020.02.09.01 is the official data processing, inversion, and visualization software for geoelectrical and electromagnetic data collected with IRIS Instruments’ acquisition systems (like the Syscal, Elrec, or TDEM systems). The software provides a complete workflow from importing raw field data, performing quality control and filtering, to running 2D/3D inversions that generate subsurface models of electrical resistivity and chargeability. These models are used to map geological structures, aquifer boundaries, contamination plumes, mineral deposits, and voids.
IRIS Instruments Electre Pro is a specialized geophysical data processing software designed for Geophysicists, Hydrogeologists, Environmental Consultants, Mineral Explorationists, Geotechnical Engineers, and Academic Researchers who acquire and interpret data from electrical resistivity tomography (ERT), induced polarization (IP), and time-domain electromagnetic (TDEM) surveys using IRIS Instruments’ equipment.
Raw Data Import & Management: Direct import and management of raw data files from IRIS Syscal, Elrec, and TDEM instruments, including multi-channel arrays.
Advanced Data Preprocessing: Comprehensive tools for filtering noisy data, removing spikes, applying topographic corrections, and calculating apparent resistivity and chargeability.
2D & 3D Inversion Engines: Robust inversion algorithms (least-squares, smoothness-constrained) to create 2D profiles and 3D volumes of true resistivity and IP (chargeability) from measured apparent data.
Model Visualization & Analysis: Advanced 2D/3D viewers to visualize inversion results as contoured sections, depth slices, isosurfaces, and volumetric renderings.
Integration with GIS & CAD: Tools to export inverted models and profiles to standard GIS formats (SHP, DXF) for integration with other geological and topographic data.
Survey Design & Forward Modeling: Capability to design optimal electrode arrays and perform forward modeling to test the response of hypothetical subsurface structures.
This version represents a stable release with key improvements in usability and inversion algorithms prior to more recent updates.
Enhanced Inversion Stability & Speed: Improvements to the core inversion algorithms for faster convergence and better handling of noisy datasets, especially for 3D TDEM and complex IP data.
Improved User Interface & Workflow: Streamlined menus and a more logical project-based workflow for managing multiple datasets and inversions.
Expanded File Format Support: Added support for newer data formats from updated firmware on IRIS field instruments and improved import from third-party systems.
Refined Visualization Tools: Enhanced tools for creating presentation-ready figures and cross-sections directly within the software.
