It was built for commercial purposes in order to connect Lake Paola with the Mediterranean Sea by cutting a channel between the end of the coastal dune of Sabaudia and the Circeo Promontory. This structure, seriously degraded in recent decades, is the focus of a collaborative research program conducted by the Sapienza “University of Rome”, the National Park of Circeo, the Archaeological Soprintendency of Lazio and the European University of Rome. In order to plan protection and conservation of the archaeological area an extensive campaign of photogrammetric survey has been initiated. The investigations have enabled a better understanding of the features in the area as well as the identification of individual degradation processes. The first operational step was to create a topographic network across the area by total station and GPS survey. The network included about 150 points on the ground, their visibility from the air increased through placing targets about 30 cm in diameter in the form of plastic discs coloured with high-visibility spray-paint. A flight was then conducted over the area by means of GREAL’s ultralight research aircraft, fitted with a nadiral digital reflex photocamera to ensure total image-coverage of the study area. Images and data were later processed to obtain a 3D model of the Porto Canale and a GIS-compatible georeferenced raster photo-map of the whole area.
