| 摘 要： | 文中分析河流等高线冲突的自动处理方法,按照地图综合原理,提出基于弹性力学思想的河流、等高线冲突自动检测和纠正算法。该算法实现河流等高线的冲突探测,并对目标进行受力分析,运用平面杆件弹性体的受力变形模型,得到目标的位移量。该方法在纠正冲突的同时保证目标空间关系的正确,实验证明算法具有较高效率。

| Abstract: | A method based on elastic mechanics to resolve the conflicts between river and contours is proposed in the paper according to automated generalization .Based on Finite Element Method the conflicts of targets are achieved to explore .Then the force bearing on these targets are analyzed .Using the deformation of the plane pole model elastomer ,the displacement of targets is calculated .So the conflicts of targets are corrected ,and all of the spatial relationship has been considered .Experiments show that the arithmetic is preferably efficient . |
