摘要
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。
The paper was aimed at realizing visualization of data on flood disaster,and providing decision support for disaster warning forecast. Through analysis of data on flood,a system was built for flood disaster data visualization. The data visualization technology was used to analyze the data and the analysis results were mapped onto visual images through the system algorithm,enabling users to receive visual information with terminal equipment. The research shows that the data can be mapped into graphics by flood disaster data visualization early warning system,the real-time changes of system data can ensure dynamic updating visualization results,and users may allowed to know the disaster situation at any time.
