Multi-Modal/Multi-Resolution 3D Data Acquisition and Processing for a New Understanding of the Historical City of Siena (Italy)

Ground Penetrating Radar (GPR) and laser scanning surveys reveal hidden structures beneath Siena's historic center, offering unprecedented insights into the city's ancient fabric. The SOS project integrates full-coverage GPR data with 3D laser scans of significant structures like the cathedral, processing point clouds to eliminate noise and transform them into meshes for semantic enrichment. This multi-modal approach enables the creation of a 3D Archaeological WEBGIS, enhancing archaeological data visualization and conservation efforts. The study demonstrates how advanced geospatial technologies can uncover buried anomalies, providing a foundation for improved urban preservation strategies.
