Input data for calculating the resistance model: apparent resistance, signal-to-current ratio.Stationary data and data obtained in motion, monitoring.

Data obtained during galvanic grounding of electrodes and non-contact sounding data.Coordinates along the profile lines, rectangular, geographic, and X,Y,Z coordinates.Positions of electrodes: ground surface, borehole, borehole- borehole, ground surface-borehole, surface of the water area, in the water column, bottom of the water area, ground surface-water area.Any type of survey arrays and measurement configurations, arbitrary spacing of electrodes, including vertical electrical sounding (VES).Besides, the program implements an algorithm for creating a protocol for cross-hole observations, taking into account the verification of unstable values that are sensitive to errors in the electrode geometry. Measurement configuration can be saved in Syscal sequence, ABEM sequence, MAE sequence, AGI sequence, and MAE instrument formats. The program allows to create measurement protocols for the following arrays of electrodes: 2-electrode (Pole-Pole,A-M), 3-electrode (Pole-Dipole, A-MN), dipole (Dipole-Dipole, AB-MN), Wenner (A-M-N-B), Schlumberger (A-MN-B), and Gradient (A-MN-B). ZondRes2d solves a wide variety of tasks from mathematical modeling, observation system selection, data quality and sensitivity analysis, to field data processing, inversion, and interpretation.Ī user-friendly interface and a wide range of data presentation options make it possible to solve the set geological problem in the most efficient way. ZondRes2d software is designed for 2D interpretation of electrical tomography data by resistivity and induced polarization (IP) methods during land, borehole, and offshore surveys.
