Contributi alla carta archeologica della Tenuta di Castelporziano: GIS, survey e remote sensing

This paper enhances the archaeological mapping of the Castelporziano presidential estate through an integrated approach that combines GIS, multi-temporal aerial photo interpretation, GNSS-supported field surveys, LiDAR-derived DTM analysis and 3D laser scanning. The investigation, focused on the coastal area of Capocotta and the imperial villa of Tor Paterno, updates previous cartographic documentation (Carta della zona litoranea di Castelporziano) and records structures previously undocumented, primarily due to the significant constraints imposed by dense vegetation cover. The georeferencing of historical maps (Carta Topografica del Lazio) and the aerial photographs have enabled a redefinition of the ancient settlement layout and improved its spatial accuracy. At the same time, preliminary research conducted in the northern sector highlights the settlement potential of this territory, despite limited surface visibility. The currently available data point to a significant presence of rural villas dating from the late Republican to the early Imperial period.
