REMOTE SENSING AND CITY INFORMATION MODELING FOR REVEALING THE COMPLEXITY OF HISTORICAL CENTERS

Abstract. Historical centers represent the outcome of transformations and stratifications cities across centuries. The knowledge a historical urban environment requires an analytical methodology articulated on several interconnected levels investigation to model multi-layered complexity that encompasses geometric stylistic features places (blocks irregularities, narrow streets, stratified buildings), accessibility (pedestrial zone, no flyzone), use existing data (GIS, cartographies). Today challenge for is dual: one side make expeditious technologies acquire data, other create 3D city models allow manage, visualize, enquire these in unique digital ecosystem. Our research deals with multi-sensor acquisition, evaluation integration aim creating informed responsive (CIM) constitute synthesis survey conducted become support simulations various contexts (seismic risk, hydraulic, energy performance).
