Integration of multisensor data: an experiment in the archaeological park of Egnazia (Apulia, Southern Italy)

In this paper, we present a case study conducted in the archaeological park of Egnazia (Apulia, Southern Italy) based on the integrated use of two different ground-penetrating radar systems plus a magnetometer. The surveys were carried out using a pulsed ground-penetrating radar system, a prototypal reconfigurable stepped frequency ground-penetrating radar and a high-resolution magnetometer. The most important anomalies identified are ascribable to the presence of a massive building structure mainly consisting of masonry, probably dating from the Roman age. Emphasis is on the integration of the results, which has made it possible to produce enhanced images. In particular, two different approaches based on (i) algebraic and (ii) RGB combinations of the data gathered with the three sensors are illustrated and discussed.
