Dalla terra al cielo e ritorno. Rotzo (VI): Un caso di telerilevamento archeologico integrato

The paper presents the results of a research focused on the acquisition and analysis of satellite and aerial data for the study of the late Iron Age village of Bostel, in the municipality of Rotzo (VI, Italy). The settlement, currently excavated by the University of Padova, was investigated through a systematic campaign of aerial survey thanks to the funding provided by the University in favor of the Horus Project. UAV-captured images were processed with Agisoft PhotoScan and a high resolution Digital Elevation Model (DEM) of the area was created using the Structure from Motion technology. DEM data were treated with different visualization techniques, such as hillshade, Sky-View Factor, Local Relief Model, slope and flow direction. All identified anomalies were cross-validated with those present on multi-band satellite images WorldView 2 and with field surveys. This redundancy favored their interpretation as structures linked to the spatial organization of the protohistoric settlement.
