| 摘 要： | 新一代天气雷达网建设已经具有相当规模,全国近150部雷达投入业务运行,但雷达探测数据业务应用大都还是常规的二维图像分析。基于单部天气雷达探测基数据分析,以三维地理信息系统为基础平台,探索在地理空间的三维云体显示分析技术,包括雷达探测数据在地理空间处理技术;探索雷达探测数据应用等值面体和实体绘制技术等构建三维云体的可视分析方法,并应用天气雷达实际探测数据在3DGIS地理空间构建了具有三维特征结构的云体,从多个视角研究分析了天气雷达探测的云体结构。

| Abstract: | There are presently about 150 radar sets in operation in the CINRAD network, but radar detection data are still displayed mostly on conventional 2D images in operational application. The volumetric cloud data are reconstructed based on the single radar base data and the 3D Geographic Information System (3D GIS). The geographical spatial processing technology of radar base data and 3D cloud volume visualization technology such as volume rendering for isosurface based on 3D grid data are discussed. It provides a new perspective to understand the cloud volume structure for radar base data analysis. |
