The presentation by Dr Paul Cureton, from the Data Science Institute ImaginationLancaster at the University of Lancaster, provided an overview of the Lancaster City Information Model (LCIM), a project in partnership with Garsdale Design, Esri UK, Cyber City 3D and Bluesky International Inc. Paul spoke about the taxonomy of visions across the centuries to identify dominant factors before setting out the challenges in creating a city information model, including open-data, geo-design and co-designing urban systems: “we need better data and insights and to share our visions of cities”. Discussing digital twins and the requirement of a framework and (Gemini) principles as presented by the Centre for Digital Built Britain’s National Digital Twin Programme, Paul expressed the importance of open data to establishing a city information model in the journey towards a digital twin. Concluding the presentation Paul described four essential components of the Lancaster City Information Model as: open data; multi layered; virtualised; and collaborative.
