Saint John Baptistery in Florence (Italy): Studies for Conservation of the External Marble Cladding

A comprehensive digital model of the Saint John Baptistery's external marble cladding, created using laser-scan surveys and GIS technology, has been developed to support its conservation. This model captures detailed geometric, geological, and historical data on all tiles, ashlars, inlays, and columns, enabling real-scale spatial analysis and management. The study identified multiple marble types through expert in situ surveys, integrating findings into a geodatabase accessible via web-based platforms. This approach provides an innovative tool for monitoring, querying, and updating conservation efforts, ensuring the long-term preservation of this UNESCO-listed 11th-century landmark.
