中文摘要：

针对目前专题地形图的成图方式比较单一,提出基于坡度与光照模型的雷达点云地形数据成图方式解决这类问题,呈现具有三维立体效果的成果图。利用该成图方式完善基于坡度进行雷达地形数据分类时偏差与破碎地形的处理,同时应用于山脊线点、山谷线点以及山顶点等特殊地形点的提取,使得水文分析、地形分析等操作简单方便。

英文摘要：

At present,the method of thematic map is relatively simple,but the terrain data of radar point cloud based on slope and illumination model can solve these problems. The method can improve the classification of the terrain data of radar based on slope,and the processing of the broken terrain,and can be used to extract the special terrain points,such as ridge line,valley line,and the peak point.
