Gaining Momentum

Snap4City is a verifiable, high-utility open-source platform for smart cities backed by the University of Florence and FIWARE, with proven deployment in over 40 locations. However, the submission itself is of low quality, containing lazy or exaggerated claims (e.g., 'most people have used my product', 'audience: everyone') that contradict the professional nature of the project. The score reflects the strong technical and real-world value of the software, heavily penalized by the poor credibility of the specific form responses.

Description
Snap4City is a 100% open-source FIWARE Platform and Solution developed under the coordination of Distributed Systems and Internet Technologies (DISIT Lab) of the University of Florence, Italy. It supports cities and businesses to improve performance and reduce costs by connecting all management and control domains. Snap4City is a data management platform that helps communities and organizations manage data with on-cloud and (or) on-premises solutions. We currently operate in more than 40 locations in Italy, Spain, France, Bosnia-Herzegovina, Finland, Belgium, Greece, Croatia, Israel, and Sweden. The platform currently has a wide range of activities in the smart city and IoT/IoE domains (Internet of Things/Internet of Everything): defining city strategies, implementing control rooms, realizing ethics- and explainable AI solutions, and computing KPIs which are used daily in both city and industry management. In this extensive range of solutions, Snap4City is compliant with more than 120 protocols, and it is interoperable with GIS (Geographical Information Systems), BIM (local Digital Twin), CKAN, and IoT Networks protocols (IOT protocols). The usage of Snap4City has brought about improvements and has been of great benefit to a wide range of situations. The very reasonable costs for implementing changes, to be done directly by city operators, have impressed many users. Snap4City can be freely installed on-premises with its entire solution components. Its impact has been demonstrated in many solutions, pilots, projects, and trials. In 2019, DISIT Lab won the Select4Cities PCP of EC and the ENEL-X open data challenge one year later. Snap4City is also one of the platforms of the EOSC (European Open Science Cloud). DISIT (University of Florence) is proud to be a Gold Member of FIWARE and an official FIWARE Platform and Solution, certified Consultant, certified Trainer, and provides two certified FIWARE Experts.
