Uncovering the challenges of urban digital twins: Identifying and ranking the barriers to operating digital twins in cities

To encourage discussion of the challenges hindering the design and implementation of digital twins, the authors have ranked them based on a systematic literature review combined with an expert survey.

Challenges of urban digital twins: A systematic review and a Delphi expert survey

Many challenges to operate digital twins remain, hindering their design and implementation, and are rarely discussed. Furthermore, issues of social and legal nature are often overlooked. We identify the challenges of operating digital twins in the urban context through a bifurcated and multi-dimensional approach: a systematic literature...

Linking spatial data: Automated conversion of geo-information models and GML data to RDF

Linked data provide an alternative route for the dissemination of spatial information compared to the traditional SOA-based SDI approach. The traditional approach has provided a wealth of standardized and structured location data based on Geography Markup Language (GML), while linked data provides an open mechanism for sharing and combining this...

Advancing Open 3D Modelling Standards in National Spatial Information Policy

Individuals and organisations around the world - facing extraordinary challenges and new opportunities - are together engaged in numerous projects, involving natural and built environments. Spatial information policy is at the heart of these projects. The information technologies available enable individuals to observe, measure, describe, map...
