为实现洪涝灾害数据的可视化,为灾害预警预报提供决策支持。通过分析洪涝灾害相关数据,构建洪涝灾害数据可视化预警系统,采用数据可视化技术对数据进行模拟分析,通过系统算法将分析结果映射为可视化的图形图像,实现用户在终端设备接收可视化信息。研究表明,通过洪涝灾害数据可视化预警系统可将数据映射为具有洪涝灾害等级值的图形图像,系统数据的实时变动能够保证可视化结果的动态更新,用户可随时跟踪了解灾害情况。
In order to visualize the flood disaster data and provide decision support for the early warning and forecasting of disasters. By analyzing the related data of flood disaster, a visual early warning system of flood disaster data is constructed. Data visualization technology is used to simulate the data and the analysis results are mapped into visual graphic images through the system algorithm so that the user can receive the visual information at the terminal device. The research shows that the data can be mapped into the graphic images with the level of flood disaster through the visual warning system of flood disaster data. The real-time changes of the system data can ensure the dynamic update of the visualization results, and the users can keep track of the disaster situation at any time.
