A 3D virtual geographic environment for flood representation towards risk communication
🤖 AI Summary
Existing flood risk research overly relies on specialized numerical models, hindering comprehension and application by non-expert stakeholders and thus limiting the effectiveness of risk communication. To address this, this paper proposes a three-dimensional visualization framework integrating Virtual Geographic Environments (VGE) with flood risk communication. The framework synthesizes hydrological simulation outputs, multi-source geospatial data, 3D modeling, GIS, and virtual reality technologies to enable spatiotemporally dynamic, interactive, and photorealistic flood inundation scenario visualization. It overcomes the limitations of conventional static two-dimensional representations, substantially enhancing the intuitiveness, accessibility, and public cognitive efficiency of flood risk information. As a result, it provides an operational, user-centered visualization support tool for public engagement and emergency decision-making—constituting a significant methodological innovation in transitioning flood risk communication from an expert-driven to a user-centered paradigm.
