摘要
针对气象雷达基数据的空间特征,划分其为雷达投影面空间和雷达立体空间,对这两种雷达空间构建点阵模型,为气象雷达信息的多维表达和分析算法提供模型支撑。结合研究区域的地表信息,调用可视化开发包(VTK)实现对点阵模型的可视化表达。在模型的支持下,集成地表信息的多维可视化表达不仅可以实现传统的二维雷达图像表达,还可以利用气象雷达体扫描数据实现三维表达,有利于气象人员直观地研究和分析雷达回波的结构特征。
According to the spatial characteristics of radar data,the radar projection plane space and the radar stereo space are divided into two kinds of radar space to construct the lattice model,whichprovides model support for the multidimensional representation and analysis of meteorological radar information.Combining the surface information of the research area,the visualization development package VTK is used to realize the visual expression of the lattice model.Under the support of the model,the visual expression of integrated terrestrial information is no longer limited to the two-dimensional form.The three-dimensional representation can display the radar details more comprehensively,which is helpful for the meteorological personnel to study and analyze the structural characteristics of radar echo.
