ARGOS is a geospatial digital twin of Kefalonia. It answers questions: which buildings are outside the 15-minute fire envelope, which ravines flood first, which beaches are exposed today. Built from Copernicus Sentinel-2, Copernicus DEM, and OpenStreetMap. Every model carries its evidence note: what was tested, what passed, what failed, what is unvalidated. The methodology is public. The data is open.
