Abstract:
1. A device for carrying out geoelectric mapping of a ground area, comprising: electrodes including supply electrodes and potential measurement electrodes, a power supply supplying power to said supply electrodes during a measurement period, a voltage measuring device connected to said potential measurement electrodes for measuring potentials therebetween, an endless loop continuously rotated about first and second axes displaced apart such that a portion of the endless loop between said first and second axes lies in contact with and conforming to said ground area between a beginning point of contact and an ending point of contact for a period of time during which the portion of the endless loop is stationary with respect to said ground area; and the electrodes being disposed at an outside surface of the endless loop which revolves and is moved continuously during the geoelectric mapping over the ground area to be investigated in such a manner that the supplying electrodes and the potential measurement electrodes are at rest on the ground along with said portion of the endless loop so that the ground area to be investigated during each individual measurement is stationary with respect to said supply electrodes and said potential measurement electrodes during said measurement and while said endless loop is continuously rotated.
