The main focus is on DC and AC resisitivity methods however modules for seismic interpretation are planned for the near future. The package has been developing during the 21st century and includes applications for electric prospecting, seismic, magnetic and gravity surveys.
The ZOND software package is oriented mainly for near surface geophysics. Many of these software are for seismic data interpretation. Depending on the nature of the application, they encompass many different directions in geophysics. ZOND software package – Software for the interpretation of geophysical data are widespread. Support for mult-core CPUs is now available with RES3DINVx32 and RES3DINV圆4. On a modern quad-core based microcomputer, the data inversion takes less than a minute for small surveys with 200 electrodes in a flat area, to a day for extermely large surveys with with thousands of electrodes in rugged terrain. It now supports parallel calculations on multi-core CPUs that significantly reduces the inversion time for very large survey grids. In addition to surveys with a traditional rectangular grid of electrodes, it also supports surveys with trapezoidal grids and even arbitrary electrodes arrangements which is common in rugged and/or forested areas. Screenshot of the program Res2Dinv showing ERT inversion method: a cross-section of apparent resistivity measured. It supports surveys with up to about 10000 electrodes and 150000 data points. To reduce costs to the user, RES3DINV is sold as a combined package with RES2DINV which costs only about 25% more than the RES2DINV program alone. where the main structure is a two-layer model with a resistiv ity of 10 m and a thick ness of 5. As an example, Figure 8 shows a 2-D model. 3D surveys are more time-consuming and expensive to carry out, but could be useful for very complex geological situations. the interpreted layer resistivity and/or thickness. RES3DINV is the 3D resistivity and IP inversion software, and it is probably the first widely available commercial software of this type. Multicore CPU support is now available in RES2DINVx32 and RES3DINV圆4 The program supports survey lines with up to 16000 electrodes and 27000 data points. It is probably an order of magnitude faster than some other commercially available 2D inversion software. In addition to the standard Wenner (alpha, beta, gamma), Wenner-Schlumberger, pole-pole, pole-dipole, inline dipole-dipole, equatorial dipole-dipole arrays it also supports non-conventional electrode arrangements. Besides normal land surface surveys, it also supports underwater and cross-borehole surveys. Geotomo Software – RES2DINV is the 2D resistivity and IP inversion software. Two-dimensional (2D) electrical imaging surveys are now widely used to map areas of moderately complex geology where 1D resistivity sounding.

3.59, Rapid 2-D Resistivity and IP Inversion Using the Least-Squares Method (Geotomo Software, Malaysia, 2010). Like RES2DINV, it is completely automatic and the user does not even have to supply a starting model. More details on the functionality of the software can be found by downloading the user manual, demo-version or by watching video reviews and tutorials. Using two-dimensional or three-dimensional inversion techniques additionally for evaluation, this method is known as Geoelectric Tomography. It is found in the ‘Manuals’ folder of the DVD/USB provided. The detailed instructions for using the programs are given in electronic form as the Res2dinvx32圆4.pdf file.
This type of geoelectric measurement is called Multielectrode Geoelectrics. This manual is a very brief guide to help you in installing, and getting started in using the Res2dinv program.

GeoTest is a software for controling geoelectric equipment in combination with many electrodes.
