摘　　要：针对当前矢量图中为等高线标注高程值的方法需要人工辅助操作较多的情况,提出并实现了一种自动化程度较高的矢量等高线高程值自动标定的方法。该方法以一个基准点高程值和等高距为依据,完全自动地计算矢量图中所有等高线的高程值,同时还可以选择性地设置若干参照点高程值用于检验计算结果是否准确。该方法原理简单,运算速度快,具有一定的实用性。More artificial work is now needed to complete the work of labeling contour in vector map generally. An algorithm was proposed and implemented which could finish the work more automatically. The algorithm calculate the height value of every contour based on height value of one point and contour interval, and man can chose some alternative point to check the result of labeling depended on the height value of these points, The algorithm is simple, rapid, and useful.
