摘　　要：本文针对纸质地图数字化后位图数据的等高线矢量化问题进行了讨论。在对数字化地图等高线的提取和线状特征两种方法分析研究的基础上,提出了一种地图位图等高线提取的新方法,并以此开发了一套基于VC++开发平台的软件系统。用实际位图数据对该系统进行的实测表明,该方法有效,结果与实际相符。The vectorization method for contour lines in digital maps is discussed. Based on studying the two proposed methods for the extraction of contour lines and llne features, a novel method for the extraction of contour lines from a digital map is put forward in this paper. And a VC＋＋-based software system is developed. The experimental results verified by real hit-map data show the method is effective.
