| Definitionskos:definition | This position paper is aimed at city officials and domain professionals working in an urban data context. Its goal is to clarify the concept of Urban Digital Twins (UDT) and to position it in regards of Digital Twins in general as well as the emerging Metaverse. Overall, the UDT concept is an approach to understand characteristics and processes of the built environment at the scale of a city. Between climate change and various demographics, dynamic cities are facing challenges that are becoming more complex to solve. Most of the time solutions have to be imagined with a system of systems approach and cannot be solved in silos. The paper represents the current state of the discussion about UDTs in the Open Geospatial Consortium (OGC), a geospatial community and standards organization. Around 3 use cases, climate change adaptation, urban transformation, and urban air mobility, this paper identifies benefits of using a UDT and explain the role of Geospatial Information (GI) and how it can contribute to an UDT. UDTs is a digital representation of the city where elected representatives and professional stakeholders can access and contribute to a common reference model to collaborate, achieving positive outcomes for the citizens. UDTs reveal insights at the intersection of the natural and built environments and human activities. They provide the means of enabling simulation scenarios and plan possible interventions as well as tracking measurable evidence of any changes in the real world. In a mature state, UDTs will establish effective feedback loops between the virtual and the true, physical environments. From discussions with elected representatives, professionals, and also based on OGC member experience on projects, it is acknowledged that the process of building an UDT might seem daunting (as outlined in the paper by [Lei, 2023]: Challenges of urban digital twins: A systematic review and a Delphi expert survey). This paper presents a pragmatic approach based on OGC standards for each use case, building on location and GI as the foundation. This approach calls for an effective data strategy and suggests that a project-based approach with a vision of building a UDT is the most efficient path. This concept of UDT, although often mentioned in the media, is still fairly new in practice and the governance of that type of platform is still a challenge. OGC is keen on supporting and collaborating on projects to help create the best practices on that matter. |
