摘　　要：采用Eclispe RCP平台,利用Oracle数据统计出闪电数据,使用ESRI提供的ArcEngine组件实现反距离加权插值(IDW)方法,同时,加入Job后台任务处理机制,避免数据在导入过程中假死机的现象.结合南京地区的闪电数据,自动绘制出闪电强度等值线.结果表明:该方法的结果反映了南京地区闪电的空间分布规律.Lightning intensity contour is one of the most basic parameter of lightning activity.The most critical part of drawing of Lightning intensity contour is as follows.Generate continuous lightning intensity grid map by lightning location data for spatial interpolation and then link the points whose values are equal.The research involved in Oracle database to count lightning data,use the ArcEngine component which provided by ESRI implemented the inverse distance weighted interpolation(IDW)method,and combine with lightning data in Nanjing,automatically drawing the lightning intensity contour based on Eclispe RCP platform for the first time.The results showed that: the results through method reflect the spatial distribution of lightning in Nanjing,which bring researchers great convenience.
