摘要
The invention relates to a method for processing georeferenced electrical resistivity measurements for electrical ground mapping. The area of a ground to be mapped is cut into a thin grid of points. According to the invention, measuring means enable to obtain n parameters (n being equal to at least 3) characterising the electrical resistivity at a given point at n different depths. Positioning means also enable to obtain, for a number k of measured points, an absolute positioning measurement and k relative displacement measurements. The three sets of measurements obtained are sent to a microcontroller which synchronises the acquisitions. The data sent by the microcontroller to a computer is processed digitally and in real time. A profile showing the sequential variations for a given depth of the ground resistivity through the area studied and a map showing the position of the measuring means are finally visualised simultaneously and in real time on two different display windows. ;Possible applications in Precision Agriculture and the prospection of archaeological sites.
