Non-Invasive Heritage Monitoring System and Analysis of Deterioration Processes Caused by Climatic and Anthropogenic Effects: The Case of the Inca Site of Ranchillos (Mendoza, Argentina)

A significant deterioration of the Inca site Ranchillos, part of the UNESCO-listed Qhapaq Ñan Andean Road System, has been quantified through a non-invasive monitoring system. The study reveals a loss of 313.99 linear meters (22.61% of total wall length) since 1956, exceeding previous estimates and highlighting the impact of climatic and anthropogenic factors on heritage conservation. Utilizing UAV-based image comparison technology, researchers implemented a management plan to track structural changes over time, providing critical data for improving preservation strategies at this key archaeological site.
