Urban Digital Twins in Practice: A Survey-Based Analysis of Data Integration Levels and Approaches

Data integration is a significant technical challenge that hinders the full implementation of Urban Digital Twins (UDTs). Given their data-driven nature, UDTs rely on the integration of heterogeneous data sources, schemas, and structures. This process is inherently complex due to the diversity of techniques and systems...

Semantic Surface Integration in CityJSON-Based Urban Digital Twins: A Rooftop Photovoltaic Potential Use Case

Urban digital twins provide an integrated framework for combining semantic 3D city models, simulation results, and interactive visualization in support of urban energy analyses. While existing approaches effectively represent results at the building scale, extending this capability to individual semantic surfaces remai...

Towards Submission-Stage Validation in BIM-to-Cadastre Workflows: Assessing IDS 1.0 for 3D Condominium Registration in Morocco

BIM models submitted for three-dimensional condominium cadastral workflows must satisfy a minimum set of conditions before they can support downstream transformation and legal registration. Using a Moroccan condominium case study, this paper investigates how far Information Delivery Specification (IDS) 1.0 can support...
