This thesis investigates the enhancement of geomatic survey and analysis through the integration of artificial intelligence (AI) for the digital documentation of archaeological heritage, with particular emphasis on submerged and underground environments. Building on the interdisciplinary foundations of archaeology and the established application of remote sensing technologies, the research addresses the contemporary demand for innovative, non-invasive, and sustainable documentation methodologies, in accordance with the principles set forth by the Faro Convention. A series of case studies conducted in Pompeii’s Regio II—specifically the Amphitheatre, the Domus of Riti Magici, and the Praedia of Julia Felix—serve to evaluate the application of advanced geomatic techniques, including multispectral UAV photogrammetry, lidar scanning, and Mobile Mapping Systems (MMS).
