However, the program can also handle data sets with a non-uniform electrode spacing.įigure 1. The survey is usually carried out with a system where the electrodes are arranged along a line with a constant spacing between adjacent electrodes.

Many different multi-electrode systems have been developed over the past 25 years using different arrangements of the cables and measurement strategies (Loke 2014). It is a Windows based program that also supports multi-core CPUs.įigure 1 shows an example of the electrodes arrangement and measurement sequence that can be used for a 2-D electrical imaging survey. RES2DINV圆4 is a computer program that will automatically determine a two-dimensional (2-D) resistivity model for the subsurface for the data obtained from electrical imaging surveys (Dahlin 1996 Loke et al. The Res2dinvx32圆4.pdf file has detailed instructions for using the software and should be used as the manual. This is a very brief guide to help you in installing and getting started with the program.

Typical display output showing the measured and calculated apparent resistivity pseudosections, and the inversion model section. Sequence of measurements to build up a pseudosection using a computer controlled multi-electrode survey setup. Dongles should be treated in the same way as any physical assets such as computers and insurance should be taken out in case it is lost or stolen.įigure 1. Please contact for the cost of a new dongle if it was lost or stolen. Important Notice: We cannot provide free replacements for lost or stolen dongles that were in the possession of the end user.
