Integrazione di database spaziali multiscala in ambito urbano

An information data infrastructure is one of the key to assure efficiency and sustainability for urban processes management. In this field spatial data management plays a central role with a focus on thematic and geometric integration, multi-scale modelling and flexibility to specific needs. These goals can be achieved through the provision of specific standards and tools for data modelling and information retrieving. The widening of the application fields of GIS to the architectural representations of the cultural heritage documentation and consequently the 3D data management support are two of the major issues for filling the gap between the CAD and GIS and their cultural and productive background. Her will be presented some preliminary issues of a test on spatal data integration in a XML based data structure following the OGC's CityGML specifications. The model implementation will focus on the multiscale and multiview modelling tools of standard as a first stepo for the management of a 3D spatial database through XML based application tools.
