Remotely Piloted Aircraft Systems are devices increasingly widely used in archaeology. Whether winglets or multi-rotors, the integration with many kinds of sensors for documentation, analysis and monitoring, allows for a greater and more accurate amount of information than traditional survey techniques. In particular, aerial imagery contains a quantity of data well beyond simply the “view from above”, if acquired with appropriate methodologies and approaches. In this light, the photogrammetry extrapolates precise and accurate 3D metric information through the interpretation and measurement of photographic images. As case studies, we illustrate the excavations carried out by the Scuola Normale Superiore and the University of Pisa in the area of the ancient Agora of Segesta (TP) and in the Sanctuary of Punta Stilo at Kaulonia (RC), where the RPAS has been used for the low altitude 3D survey. The description of the strategy, the procedure adopted, the time required for the processing of the survey and the results obtained are accompanied by a critical reflection on the great potential but also the limitations of these devices, not least the rigid regulations recently issued by ENAC.

Abstract
Remotely Piloted Aircraft Systems are devices increasingly widely used in archaeology. Whether winglets or multi-rotors, the integration with many kinds of sensors for documentation, analysis and monitoring, allows for a greater and more accurate amount of information than traditional survey techniques. In particular, aerial imagery contains a quantity of data well beyond simply the “view from above”, if acquired with appropriate methodologies and approaches. In this light, the photogrammetry extrapolates precise and accurate 3D metric information through the interpretation and measurement of photographic images. As case studies, we illustrate the excavations carried out by the Scuola Normale Superiore and the University of Pisa in the area of the ancient Agora of Segesta (TP) and in the Sanctuary of Punta Stilo at Kaulonia (RC), where the RPAS has been used for the low altitude 3D survey. The description of the strategy, the procedure adopted, the time required for the processing of the survey and the results obtained are accompanied by a critical reflection on the great potential but also the limitations of these devices, not least the rigid regulations recently issued by ENAC.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
