基于Android移动设备的闪电可视化功能设计与应用

摘要

闪电具有突发性、瞬时性、三维性等特征.其特征导致闪电监测数据基于web端的即时处理和显示受到限制,小范围内的雷电临近预警服务受到影响.基于Android移动设备利用GPS定位技术开展闪电数据可视化研究具有重要的意义.将闪电实时监测数据与GPS位置数据结合,集合采集、转化、整合和数据叠加等逻辑过程,通过直观添加覆盖物的方法,在Android移动设备地图上精确标注闪电发生的地点、强度以及发生距离等信息,实时显示用户附近20 km以内的闪电情况.用户据此及时采取相应的防御措施,减少雷电灾害导致的生命和财产损失.%The lightning has the features of sudden,instance and three-dimensionality.These features lead to the limitation of instant processing and display of the thunder monitoring data based on the Web end,and the lightning nowcasting in the small range has been influenced.Therefore,the visualization of lightning data based on the Android mobility device by means of the GPS location technology has great significance.In combination with the real-time monitoring data of thunders and lightning and the GPS location data,assembling the logic processes like the collection,transformation,integration and data superimposing,remarking the information like the location,intensity and the occurrence distance of thunder,and displaying accurately on the mobile device map through the method of adding the cover intuitively,the lightning situation can be shown in real time within 20 km around the user.The users can take the corresponding precautions in time in order to reduce the life and fortune loss caused by thunder disasters.
