THREE-DIMENSIONAL INTERPRETATION OF ELECTRICAL TOMOGRAPHY DATA BY RESISTIVITY AND INDUCED POLARIZATION ZondRes3d program is designeed for three-dimensional interpretation of electrical tomography resistivity and induced polarization data in land, cross-borehole and marine variants. Electrical tomography is a whole technique including the method of field observations and technology of processing and field data interpretation. Its feature is multiple reusing as a source and receiver just the same electrodes position, fixed on a site. 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. For interpretation of electrical tomography data two- and three-dimensional models is used . It significantly extends the range of electric prospecting solved problems due to sections investigating that are considerably different from «classic» horizontal-layered. Resolution and thus interpretation quality of electrical tomography is closely connected with the number and density of measurements on one site. Their number usually reaches first thousand that is why the question on field measurements efficiency has basic importance and in many aspects defines possibility of practical using of this method. Special equipment with programmed automatic switching of electrodes is applied for reaching of maximum effectiveness of field works. The technique of three-dimensional electrical tomography means a special measurement technique with use of a considerable number of switched electrodes (some electric prospecting cables) while number of measurements reaches ten thousand.
