基于Flex和Google Map的雷电数据可视化研究

针对实现雷电数据可视化的关键技术,采用Flex技术结合Google Map构建了雷电数据可视化平台,重点研究了闪电定位数据、地面电场探测数据以及雷达栅格数据的可视化方法。由于GoogleMapAPI无法满足一些业务需求,设计了自定义类实现信息窗口交互和绘制圆的功能。通过对比传统平台的展现效率可知,采用Flex技术能有效地优化雷电数据的可视化效果,平衡系统运行负载,为雷电数据可视化提供了新的平台支持,对雷电WebGIS进行了有益的探索。

Research on Lighting Data Visualization Based on Flex and Google Map

To realize the key technology of lightning data visualization,this article using the Flex technology in combination with Google Map constructed the lightning data visualization platform,and discussed the visualization methods about lightning positioning data,lightning monitoring data and lightning raster data in detail.Because Google Map API can't meet some of the business requirements,this paper designed custom class to implement the information window interaction and drew round function.Through comparing with the show efficiency of traditional platform,the result is that the Flex technology can effectively optimize the lightning data visualization effect,balance system run load,provides a new platform support for lightning data visualization,takes the beneficial exploration for lightning WebGIS.
