Data Quality in Urban Digital Twins: Challenges in the Virtualization of Florence’s Historic Heritage

High-resolution digital tools, such as the Digital City & River Twin (DiC&RT) framework, are essential for urban planning and heritage protection in historic city centers like Florence's. The study reveals that data quality, consistency, and granularity are critical for the effective operation of Urban Digital Twins in managing resilience and conserving heritage. It addresses challenges related to building density, visual occlusion, and data heterogeneity by integrating MMS surveys and UAV photogrammetry, proposing multi-technological solutions for more accurate modeling. The research emphasizes the importance of interoperable data structures like CityGML and controlled vocabularies in multi-risk analysis, particularly for hydraulic and seismic scenarios.
