雷电监测数据三维可视化技术研究

Research on 3D Visualization Technology of Lightning Monitoring Data

为研究满足目前气象行业需求特点的全国雷电监测数据三维可视化技术,实现雷电数据的二维与三维融合交互显示,采用面向对象语言Visual Studio.Net(C#)集成ArcEngine进行雷电监测数据三维显示系统的开发,解决雷电数据在二维及三维地图上的处理与显示问题。介绍ArcEngine组件的二次开发、地图数据的处理以及二/三维间雷电数据的交互显示方法。实验结果表明,采用上述方法构建的国家雷电监测数据三维显示系统能更好地满足实际业务需求,为防雷减灾等工作提供更直观的决策支持服务信息。

On the meet the current meteorological characteristics of national industry demands lightning detection data visualization technology,the final implementation of lightning data fusion of two-dimensional and three-dimensional interactive displays.It uses object-oriented languages Visual Studio.Net（C#） integration ArcEngine for lightning detection data development of three-dimensional display system to solve lightning data in two-dimensional and three-dimensional map of the handling and display problems.The article describes the ArcEngine component of the second development,map data processing as well as two-and three-dimensional lightning data interaction between display methods.Experimental results show the practice of using the above method of construction of the national lightning detection data three-dimensional display system to better meet the real business needs,as lightning protection and provide more intuitive decision support service information.
