PRISMA applications for territorial and urban planning

The Italian Tuscany Region, as part of its competences related to the knowledges of land use discipline, has been using, promoting, and maintaining functional territorial information since the 1970s. Nowadays, this activity is carried out not only for the needs of public administration technicians related to territory planning and management, but also for freelancers and citizens free information. However, while for some types of services in administrative procedures, territorial information from an aerial platform is still preferred, attention in recent years has also shifted to the possible use of optical satellite data. For this reason, the Tuscany Region in 2018 started an agreement with ASI and begun a pilot project in collaboration with UniSI and CNR. The project, still in progress, has as its first objective the mapping of the main materials that make up the city roofs (brick, cement conglomerates, bituminous conglomerates, metal, plastic, silicon, etc.) with the goal of implementing the attributes of their Land Use/Land Cover databases that are stably issued, every 3 years, since 2007. The first results clearly express the fundamental contribution of the hyperspectral data but, at the same time, highlight some intrinsic limits to the PRISMA mission, easily to be overcome and, we hope, interesting proposals for future hyperspectral missions.
