3D resistivity tomography and GPS survey: the case of the ancient town of Cuma

The main purpose of this paper is to obtain an optimization of geoelectrical acquisition and interpretation procedure. We use an home made resistivity survey system consisting of: 1) an ac generator, 2) a receiving and acquiring unit connected through a radio-modem system, 3) a GPS unit for fast positioning of survey points. The probability tomography approach is extended to the case of a generally uneven prospection surface. Finally, we show the results of the application of the 3D resistivity tomography to the ancient town of Cuma.
