Interpolate data from land, under water, and cross-borehole surveys.

The software can handle data from any electrode array, including Wenner (a, b, g), dipole-dipole, inline pole-dipole, pole-pole, Wenner-Schlumberger, equatorial pole-dipole and non-conventional arrays. The inversion of the resistivity and IP data is conducted by least-square method involving finite-element and finite-difference methods. Supports exact and approximate least-squares optimisation methods Supports smooth and sharp constrasts inversions Supports up to 16000 electrodes and 21000 data points on computers with 1GB RAM Seamless inversion of very long survey lines using sparse inversion techniques (RES2DINV only license includes limited used of RES3DINV 3D inversion program) RES2DINV software is designed to interpolate and interpret field data of electrical geophysical prospecting (2D sounding) of electrical resistivity (conductivity) and induced polarization. The COMSYS Pro software is a program allowing to control a SYSCAL Pro-Switch resistivity-meter in multi-electrode mode, from a PC.Supports on land, underwater and cross-borehole surveys Supports the Wenner (alpha,beta,gamma), Wenner-Schlumberger, pole-pole, pole-dipole, inline dipole-dipole, equatorial dipole-dipole, gradient and non-conventional arrays. The ELECTRE Pro software allows also to import any type of sequences, manually created in ″txt″ file, in case of specific applications

Measurements (gapfiller quadripoles) that can be rejected after acquisition (by the PROSYS II IRIS Instruments software)). Optimization of sequences for higher acquisition speed (the optimization process can add some.

Definition of the levels of investigation with the possibility of multi-spacing configuration for data quality improvement.Use of any type of standard electrode arrays (dipole-dipole, reciprocal Schlumberger-Wenner, poledipole forward & reverse, cross diagonal pole-pole …).The ELECTRE Pro software allows to create automatically (accounting an estimated maximum investigation depth, user specified) or manually, some sequences of measurements with many possibilities: The ELECTRE Pro software is a program allowing to create some 2D-3D-surface/boreholes sequences of measurement for IRIS Instruments SYSCAL Pro-Switch resistivity-meters.
