The "Metropolitan Digital Fabric Project - TDM" (2017-2022) is a research, development, and training project that aims to study and experiment with new smart solutions to improve urban attractiveness, resource management, citizen safety, and quality of life.

The project studies and develops enabling technologies, particularly for distributed sensing, big data aggregation and processing, open data distribution, and complex data analysis and visualization, as well as specific vertical solutions for environmental risk protection, energy efficiency, and cultural heritage presentation. Methods and applications are being tested and validated in the city of Cagliari (Sardinia, Italy), leveraging advanced communication infrastructures and distributed sensing at a metropolitan scale.

TDM research activities are complemented by a dissemination and training plan that will include the organisation of three Summer Schools on Urban Informatics:

The project is part of a broader framework that aims to make Sardinia one of the most important regions in the development and application of innovative technologies for smart cities. In particular, project experiments will be carried out at a metropolitan scale by means of a framework agreement with the city of Cagliari and will make use of the computing and networks infrastructures of the Joint Innovation Center, located in the POLARIS Technology Park (Pula, Cagliari).

TDM is a collaborative project between CRS4 and the University of Cagliari, funded by the regional agency Sardegna Ricerche (POR FESR 2014-2020, Azione 1.2.2).
