摘要
运用移动设备和系统展示灾情信息,在突发性大气污染事故移动应急中发挥着越来越重要的作用。大气污染事故模拟灾情,如污染浓度、伤亡概率,这些数据都以文本信息存储,很难在移动端进行可视化。Geo JSON是一种用于简单地理特征集合编码的开放格式,可为移动数据可视化提供一种解决方案。论文在对Geo JSON进行分析的基础上,给出了基于Geo JSON的大气污染灾情表达格式,设计了基于Geo JSON的突发性大气污染模拟灾情的可视化流程和方法。最后,实现了移动端的大气污染灾情的可视化,并对可视化效率进行了测试分析。
It will play a more and more important role in the air pollution emergency to apply mobile device and system to display the disaster information. The air pollution simulation disaster condition,such as pollution concentration,casualty probability,is stored as a text type,and is very difficult to be visualtized on mobile terminal. Geo JSON is an open standard format for encoding collections of simple geographical features,which may provide a solution for mobile data visualization. Firstly,the expression format of the air pollution disaster condition were given based on the analysis of the Geo JSON. Then a Geo JSON-based mobile visualization flow and method for emergency air pollution simulation disaster condition were put forward. In the end,the visualization of air pollution disaster condition on the mobile terminal are implemented,and the visualization efficiency was analyzed.
