摘 要：Clear communication of information is a compulsory issue in disaster risk management. This section highlights the development of interactive tools to constantly present the most recent geo-database with multi-scale and multi-source approaches, and user-oriented graphical interfaces for simple and quick data management. A client-server structure is used to customize geo-data accessibility rights and interaction and a WebGIS service architecture is designed to offer data accessibility and effective dissemination to the user community. Different solutions are presented using a common open source environment and interoperability plug-ins: (1) WebRiskCity is an educational kit on multi-hazard risk assessment, (2) Barcelonn@ supports risk management with interoperability on spatial data and metadata, (3) Historic? is a prototype to spatially compare historical natural events and population trends, and (4) MultiRISK Visualisation Tool is a service to automatically publish multi-hazard risk analysis outcomes produced by the MultiRISK Modelling Tool.
