资源简介:
The Flood Inundation Mapping (FIM) Visualization Deck is a web-based application designed to display and compare flood extent and depth information across various temporal and scenario conditions. It provides a front-end interface for accessing geospatial flood data and interacting with mapped outputs generated from hydraulic modeling.
Core Functions:
• Flood Extent Mapping: Visualizes flood extents from modeled scenarios (e.g., 2-year, 10-year, 100-year events) and real-time conditions based on streamflow observations or forecasts.
• Flood Depth Visualization: Displays depth rasters over affected areas, derived from hydraulic simulations (e.g., HEC-RAS).
• Scenario Comparison: Allows side-by-side viewing of multiple FIM outputs to support calibration or decision analysis.
• Layer Management Toolbox: Users can toggle basemaps, adjust layer transparency, load datasets, and control map extents.
Data Inputs:
• Precomputed flood inundation extents (raster/tile layers)
• Depth grids
• Stream gauge metadata
• Associated hydraulic model outputs
Technical Stack:
• Front-end: Built with JavaScript, primarily using Leaflet.js for interactive map rendering.
• Back-end Services: Uses GeoServer to serve raster tiles and vector layers (via WMS/WFS). Uses OGC-compliant services and REST endpoints for data queries.
• Data Formats: Raster layers (e.g., GeoTIFF, PNG tiles), vector layers (GeoJSON, shapefiles), elevation models, and model-derived grid outputs.
• Database: Integrates with a PostgreSQL/PostGIS backend or similar spatial database for hydrologic and geospatial data management.
• Deployment: Hosted via University of Iowa infrastructure, with modular UI elements tied to specific watersheds or study areas.
Intended Use:
The application provides a reference and exploratory tool for comparing modeled flood scenarios, visualizing extent and depth data, and interacting with region-specific inundation data products.
洪水淹没制图(Flood Inundation Mapping,FIM)可视化工作台是一款基于Web的应用程序,旨在展示并对比不同时间维度与情景模式下的洪水波及范围与水深信息。其提供前端交互界面,可用于获取地理空间洪水数据,并对水力模型生成的制图成果进行交互操作。
核心功能:
• 洪水波及范围制图:可可视化呈现基于径流观测或预报数据生成的模型情景(如2年一遇、10年一遇、100年一遇洪水事件)与实时工况下的洪水波及范围。
• 洪水水深可视化:可展示受淹区域内的水深栅格数据,此类数据源自水力模拟(如HEC-RAS)。
• 情景对比分析:支持多份FIM成果的并排查看,以辅助模型校准与决策分析。
• 图层管理工具箱:支持用户切换底图、调整图层透明度、加载数据集以及控制地图显示范围。
数据输入类型:
• 预计算洪水淹没范围(栅格/瓦片图层)
• 水深网格数据
• 水文站元数据
• 配套水力模型输出成果
技术栈:
• 前端:基于JavaScript开发,核心采用Leaflet.js实现交互式地图渲染。
• 后端服务:依托GeoServer发布栅格瓦片与矢量图层(通过WMS/WFS协议),并采用符合OGC标准的服务与REST接口实现数据查询。
• 数据格式:支持栅格图层(如GeoTIFF、PNG瓦片)、矢量图层(GeoJSON、Shapefile)、高程模型以及模型衍生网格输出成果。
• 数据库:集成PostgreSQL/PostGIS后端或同类空间数据库,用于水文与地理空间数据的管理。
• 部署方式:依托爱荷华大学(University of Iowa)的基础设施进行部署,其模块化UI组件可适配特定流域或研究区域。
应用场景:
本应用可作为参考与探索工具,用于对比模型模拟的洪水情景、可视化洪水波及范围与水深数据,以及对区域专属淹没数据产品进行交互操作。
