2D+3D PROCESSING SOFTWARE FOR ELECTRICAL TOMOGRAPHY, BASIC VERSION In areas where the geological structures are approximately two-dimensional (2D), conventional 2D electrical imaging surveys have been successfully used. Main limitation of such surveys is probably the assumption of a 2D structure. In areas with complex structures, there is no substitute for a fully 3D survey. Supported arrays include the pole-pole, pole-dipole, inline dipole-dipole, equatorial dipole-dipole, Wenner-Schlumberger and non-conventional arrays. RES3DINVx32/x64 programs use the smoothness-constrained Gauss-Newton least-squares inversion technique to produce a 3D model of the subsurface from the apparent resistivity data alone. Like RES2DINV, it is completely automatic and the user does not even have to supply a starting model. A Intel multi-core (or compatible CPU) based microcomputer with at least 2 GB RAM and an 500 gigabyte hard-disk is recommended. It supports parallel calculations that significantly reduces the inversion time.
