等高线数字化过程中，等高线与边界是否无缝衔接关系到整个后续建模的成败。文章关于等高线与边界无缝衔接问题，在构建数字等高线数据结构的基础上，就数字等高线两端在边界内和在边界外分别编写了数字等高线首尾节点延长算法与裁剪算法，实现了数字化等高线与边界的计算机自动无缝衔接。最后通过实例验证了算法的可行性。

During the process of digital contour line, contour and the boundary’ s seamlessness or not is related to the success or failure of the whole modeling in the future.Based on construction the data structure of digital contour, as for the contour and the boundary seamless convergence, the extended algorithm and the clipping algorithm for the digital contour end-to-end node are pro-grammed to deal with the problem of the two ends of the digital contour ends in the boundary or outside the boundary, which has a-chieved the digital contour and the boundary of computer automatic seamless convergence.Finally an example proves the feasibility of the algorithm.
