Zondres2d

Basic characteristics:

• Both 32-bit and 64-bit versions are available.
• It supports any arrays of electrodes or combinations with arbitrary system of spacing and positions of electrodes. The possibility of working with different matrices (number of electrodes) in the same place.
• Measurements at the water surface and at the bottom of the water. Hole systems and cross holes. Any mixed system.
• Four ways to specify topography. Real-time editing. Strike parameter setting.
• Two ways of induced polarization reversal. Default scheme (static IP) and full waveform IP inversion for paste-paste parameters (time and frequency domain). Approximate and complete solution. Time-lapse inversion.
• Script recording for processing multiple files.
• Special options for large scale problems.
• Buffer for 5 models.
• IP data resistivity and quality control, data removal and editing module, EM removal .
• A set of tools for mathematical modeling of geoelectrical section. Standard mesh bitmap style, arbitrary layers model, and polygonal style model. Additional tools for direct gravitational, magnetic and self-potential modeling and joint inversion.
• Number of resistivity and IP inversion algorithms: smooth, focus, robust, block. Define the reference model for the inversion. Noise component suppression during inversion (robust reweighting).
• Suppression of static P/C displacements during inversion. Working with anomalous MAN AMNA matrices (method of true anomalies).
• Definition of limits for model parameters, insertion of a priori geological limits and data of holes for inversion. Assigning weights to data records. Measurement editor.
• Estimation of the quality of results based on sensitivity matrix analysis. Calculation of sensitivity, quality and DOI index .
• Crop of model edges: by angle or sensitivity level.
• Number of variants for data visualization, model and a priori information. Ability to define a semi-transparent background for the resistivity section (geological and seismic sections).
• Three-dimensional visualization of geoelectric sections along arbitrary system profiles. Maps parameter slices to various depths.
• Geological section editor and well column editor. Titled holes.
• 2D joint inversion with magnetotelluric, refractive seismic and TDEM data.
• Support for the MMR method
• Export to bitmap and vector graphics formats, excel, surfer, AUTOCAD. Set the scale of the exported image. Print images and create reports.
