VIDEOR: CULTURAL HERITAGE RISK ASSESSMENT AND MONITORING ON THE WEB

摘要

Cultural heritage is constantly threatened by several factors, such as anthropic activities (e.g. urbanization, pollution) and natural events (e.g. landslides, subsidence) that compromise cultural assets conservation and integrity over time.Italy is the country with the highest number of UNESCO cultural and natural World Heritage sites (51) containing both monuments and archaeological assets of global significance that need to be preserved for future generations; as declared and requested both by UNESCO and the European Commission. VIDEOR; the first web-service completely dedicated to cultural heritage; arises as support tool to institutions and organisations responsible of CH safeguard; with the goal to guarantee a constant and continuous monitoring of cultural assets considered to be at risk. Thanks to its services; VIDEOR allows a periodic situation evaluation; performed with the use of satellite remote sensing data (both optical and SAR) and aerial platform remote sensing data (UAVs); these last used when satellites identify a critical situation that requires deeper analyses. This constant and periodic monitoring will allow not only always updated information about the asset health status; but also early warnings launched by the operative center (NAIS) directly to experts of the responsible institutions (ISCR) after risk identification. The launch of early warnings will be essential for triggering promptly activities of preventive restoration; a less expensive way of intervention if compared to the post-event restoration; both in economic terms and in terms of historical preservation of a country.
