The first applications of method were\u00a0in 20th years of XX century. Comparative simplicity and evidence of VES\u00a0resulted in its wide distribution and development in the whole world.\u00a0Nowadays vertical electric sounding remains one of the most applied\u00a0electromagnetic methods. Other modern technologies are developed on the\u00a0basis of VES \u2013 for example, electrical tomography<\/a>, based on the same\u00a0principles that for \u00abclassic\u00bb electric soundings.\r\n

\"Main<\/a><\/p>\r\nOne of the basic requirements to application of geophysical methods is\u00a0a contrast in physical properties of study object. For \u00a0resistivity\u00a0methods (including VES) it means that the studied object must\u00a0be contrast in \u00a0electric resistivity from host rocks [MSU,\u00a02007].\r\n\r\nComfortable interface and wide possibilities of data presentation allow to solve given geological problem with maximum effectiveness. While developing software special attention was payed to comfort and simplicity of its use, variety of visualization features and account of a priori data.\r\n\r\nDepending on the interpreter\u2019s choice, software \u00a0gives different \u00a0variants \u00a0 of data interpretation algorithms. Comfortable control system allows to choose from the great number of equivalents results that will appear to be the best in geophysical and geological point of view. Conception of multi-station \u00a0interpretation is basis of the\u00a0ZondIP1D\u00a0<\/strong>software. Consequently, profile line data is considered as a reflection of geological section. It\u2019s mean \u00a0that \u00a0multi-station data of profile line is whole, and not set of \u00a0separated curves. Special windowed algorithms developed for interpretation of \u00a0profile line data are provided in the software with every curve segment P-effect\u2019s\u00a0reduction. But most software features can be used also during work with the separated points of VES.\r\n\r\nConception of multi-station \u00a0interpretation is basis of the\u00a0ZondIP1D\u00a0<\/strong>software.

Program supports both the traditional arrays (Schlumberger, Wenner or Dipole-dipole axial) and the most exotic, with an arbitrary orientation of electrodes and mixed systems, with taking account of frequency. \u00a0Electrodes (source and measuring) can be located on one line or in arbitrary configuration on the plane. Data can be imported into the program in the formats of the most popular programs such as Ipi2win, IX1D.\r\n

\"Results<\/a><\/p>\r\nAs the basic task of the program is inversion of geoelectric section parameters \u2013 few variants of inverse problem are realized in\u00a0<\/strong>ZondIP1D<\/strong>,<\/strong>\u00a0 \u00a0basic of them are: smoothed inversion \u2013 to get smooth, and focusing \u2013 to get \u00a0the piece-smooth distributing of geoelectric parameters vs depth. Because of equivalence of inverse geophysical problems, quality of the obtained results strongly depends on the amount of used\u00a0a priori data. In\u00a0Zondip1d<\/strong>\u00a0there is possibility of weight setting (Error gates) for measurements, fixing and limiting of different layers parameters, using of a priori model as reference in inversion. If the values of some section parameters are known exactly (a priori or on interpretation results), their fixing is possible before the beginning of automatic interpretation. The fixed parameters do not change during the process of inversion. Fixing of parameters is the method for \u00a0hard regularization of inversion process. The robust schemas of noise estimation are realized in the program.\r\n
