The area of soil to be mapped is divided up into a fine network of points. According to the invention, measuring means are used to obtain n parameters (n being at least equal to 3) characterising the electrical resistivity at a given point at n different depths. In addition, an absolute position measurement and k relative displacement measurements are obtained using positioning means for a number k of points measured. The three measurements obtained are subsequently sent to a microcontroller which synchronises the acquisitions. The data sent by the microcontroller are digitally processed in real time on a computer. Furthermore, two different display windows are used to view, simultaneously and in real time, a profile showing the sequential variations for a given depth in the resistivity of the soil across the area studied and a map showing the position of the measuring means. The invention is suitable for use in precision farming and for prospecting archaeological sites.
