摘要
准确识别灾情相关的空间位置是利用社交媒体数据进行灾情分析的关键。基于微博数据的台风灾情分析系统将新浪微博作为数据源,综合利用Echarts可视化类库和Leaflet地图框架展示台风灾情的时空过程,实现了动态可交互的台风灾情信息快速提取和动态可视化,能为台风灾害等突发事件提供应急决策支持。
The key to analyze the disaster situation is to identify the spatial location of disaster accurately.Based on microblog data,the typhoon disaster analysis system takes Sina Weibo as the data source,and displays the temporal and spatial process of typhoon disaster by using the ecoharts visual library and the leaf map framework.It realizes the dynamic interactive information extraction and dynamic visualization of typhoon disaster,which can provide emergency decision support for typhoon disaster and other emergencies.
