Improved Cadastral Data Management for Flood Risk Management in A BIM-GIS Compliant Environment by Engaging Stakeholders

Abstract: Flood risk management in the Netherlands is transitioning to a decentralised model that actively involves municipalities and different stakeholders, such as property owners and citizens. This research addresses the technical challenges of integrating semantic 3D city models, Building Information Modelling (BIM), and Geographic Information Systems (GIS) for improved flood risk management. A web-based platform was developed using Django, integrating cadastral data, BIM, and semantic annotations. The system incorporates Cesium-based 3D and IFC viewers to visualise both urban environments and building-level details. This study contributes to participatory flood management by enhancing stakeholder engagement, preserving semantic richness and providing a scalable framework.
