Elaborazione ed interpretazione di immagini telerilevate per lo studio sistematico delle testimonianze antropiche nel territorio. I casi di Palmyra e Selinunte

Remote sensing, through orbital, airborne or close range images, is, today, the most accurate and suitable methodology to achieve an exhaustive investigation of a defined territory. It can be regarded as a great reservoir of any document left by past human societies, who settled in the studied area, from which it is possible to recover the spatial organisation of the culture produced by those societies. The multispectral images record both the reflected and the emitted energy; the latter is linked to the nature of the soil and, in particular, to standing structures. Through surface investigation, geophysical survey and accurate georeferencing, mainly by GPS receivers, it is possible to build a topographic information system to be integrated with the known information of all the preserved documents about the settlement system within the investigated region. Two case studies are discussed here: the area surrounding Palmyra in Syria and the territory of Selinus in Sicily; both illustrate, through newly discovered evidence, the results of the applied methodology.
