Resolution and thus results quality of electrical tomography is closely connected with the number and density of measurements on the site. It significantly extends the range of electric prospecting solved problems due to sections investigating that are considerably different from «classic» horizontal-layered. For interpretation(inversion) of electrical tomography data is used two- and three-dimensional models. Such approach allows from one hand to work with a modern high-performance instruments, and on the other hand, to apply effective algorithms of modeling and inversion of resistivity and IP data. Its feature is multiple reusing as a source and receiver just the same electrodes position, fixed on a profile line. Zondres2d program is designed for two-dimensional interpretation of electrical tomography data by resistivity and induced polarization method in land, cross-borehole and water cases.Įlectrical tomography ( Resistivity imaging) is technique including both the method of field observations and technology of processing and field resistivity and IP data interpretation.
