| 摘 要： | 通视分析是常用的重要地理信息系统分析方法,在各种系统的空间分析功能中,用得较多的是直线通视,而在许多现实情况中,通视路径是一条曲线。作者根据军事上的应用需求,以炮弹弹道计算数字地形模型上的着落点为例,来初步探讨曲线通视的算法,并用实例进行了验证。

| Abstract: | The visibility analysis is an important method in GIS.The visibility analysis through the straight line has been broadly applied to many fields.In other fields,however,the path of visibility can also be curve.The author shows the feasibility of the curve visibility analysis for military use,through finding the points of fall along the shell's flight path,and proves the validity of the method. |
