Pavia 3D: Reading and decomposition of the city for the construction of dynamic databases on heritage

Urban morphology and its study for the preservation of the image of city centers represents a topic of increasing scientific interest in the representation of cultural and perceptive values of landscape, especially in a context such as the Italian one where the rich architectural heritage requires a use of innovative monitoring technologies for more conscious intervention methods. The city of Pavia, Longobard capital of Roman origins, in its dual nature of historical center and university town, starts a research that combines the protection of architectural heritage to the evolution of Smart City, through a detailed documentation aimed at virtual modeling and fruition for the restitution of symbolic values and the identity of place, seismic monitoring and urban planning evolution, which develops from first metric analysis phases of urban building units and their fronts through detection campaigns and data processing of point clouds from laser scanners. The digital database obtained, result of investigations and survey actions, aims to figure as the best appropriate representative instrument to transform buildings into multimedia information containers that will guide visitors in the knowledge of their territory and city and technical planners in the control and intervention on buildings, generating new frontiers of interaction with the virtual space where users can find themselves actors and builders of visible and "invisible" reality around them, creating the bases for the project of the City of Future.
