Res2DInv 5.0.1

Res2Dinv is a powerful 2D inversion software for ERT (DC) and IP data. The software offers a simple workflow from data import to inversion and visualization, while still offering full control over inversion parameters for advanced users.

The software is very flexible and can handle all conventional electrode configurations and custom 2D configurations, as well as underwater and cross-borehole surveys. The software supports visualization of pseudosections and inversions as well as export of the results for use with visualization and interpretation software.

RES2DINV software is designed to interpolate and interpret field data of electrical geophysical prospecting (2D sounding) of electrical resistivity (conductivity) and induced polarization. The inversion of the resistivity and IP data is conducted by the least-square method involving finite-element and finite-difference methods.

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. Interpolate data from land, underwater, and cross-borehole surveys. Easy data conversion from the most popular geophysical instruments including ABEM  Lund, Syskal, AGI, PASI, IRIS, SCITREX, etc.

It is probably an order of magnitude faster than some other commercially available 2D inversion software. The program supports survey lines with up to 16000 electrodes and 27000 data points.
