::::::English Description:::::: upports 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 and non-conventional arrays. 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) Two-dimensional (2D) electrical imaging surveys are now widely used to map areas of moderately complex geology where conventional 1D resistivity sounding and profiling techniques are inadequate. The results from such surveys are usually plotted in the form of a pseudosection (Figure 1a) which gives an approximate but distorted...

::::::English Description::::::  Over the last 10 years, there has been a revolutionary change in the resistivity (and IP) surveying method. Until the early 1990s, the resistivity method has been used as a one-dimensional (1D) tool where quantitative modelling was confined to simple horizontal layers which are not sufficiently accurate for complex geological environments. However due to recent developments in field equipment design, interpretation software and microcomputer technology, two-dimensional (2D) and even three-dimensional (3D) surveys are now practical geophysical exploration tools for environmental and engineering studies. RES3DINV is the 3D resistivity and IP inversion software, and it is probably the first widely available commercial software of this type. 3D surveys are more time-consuming and expensive to carry out, but could be...
