Urban Digital Twins – A FIWARE-based model

Abstract This article describes the use of digital twins for smart cities, i. e., Urban Digital Twin (UDTw) concept. It shows how UDTws can be realized using open source components from FIWARE ecosystem that are already used in more than 200 cities worldwide. The NGSI-LD standard is supported by European Connecting Europe Facility, Open and Agile Smart City community, Indian Data Exchange platform, Japanese Reference Model. Unlike other domains, e. g., manufacturing, where co-developed with their physical counterparts, often evolve driven different stakeholders, on time scales, as well utilizing many data sources city. builds a well-established lifecycle model Twins combines this conceptual consisting data, reactive, predictive forecasting (“what if”) twin functionalities. also AI-based technologies to extract knowledge build IoT-based infrastructure
