基于GIS的闪电参数查询系统设计与实现

Design and implementation of lightning parameters inquiry system based on GIS

基于.NET4.0开发环境、MapX5.0组件技术和SQL Server数据库开发与应用技术,利用C#编程语言,设计了闪电参数可视化查询系统.该系统将闪电定位资料与地理信息相结合,实现了地理信息的查询和编辑、原始闪电数据的存储和管理、闪电参数的查询和分析、专题图绘制和输出等功能.以武汉"1+8"城市圈(武汉市、孝感市、天门市、潜江市、仙桃市、咸宁市、鄂州市、黄石市、黄冈市)为例,展示了闪电参数查询、专题图绘制、测量工具和闪电发生位置以及雷电流强度分布查询的应用结果.

A lightning parameter inquiry system is designed and implemented using MapX5. 0,Microsoft SQL Server 2008 and C# programming language under.NET4. 0 development environment.Combined lightning data with geographic information,this system can realize functions of query and editing of geographic information,storage and management of original lightning data,query and analysis of lightning parameters,and drawing and output of thematic maps.For instance,this paper takes the Wuhan city circle,which includes 9 cities of Wuhan,Xiaogan,Tianmen,Qianjiang,Xiantao,Xianning,Ezhou,Huangshi and Huanggang,to implement this GIS based inquiry system,and shows the results of lightning parameter inquiry,thematic map drawing,position of lightning occurrence and observation station,and distribution of lightning current intensity.
