The hypogea of the Punic necropolis of Nora represented a testing ground for the use of photogrammetry as an archaeological survey tool in a highly critical context, both from the point of view of the survey itself and from the point of view of the understanding and dissemination of the underground evidence. The study describes the acquisition techniques and the tools used to share the 3D models, both among the research team and with external users, with a specific focus on web-based tools (Potree).
