摘要 针对数据更新中常见的河流偏离山谷线这一空间不一致问题,提出了一种基于矢量投影法的快速、准确地提取山谷点的方法,并利用提取出的山谷点来检查与其相关河流的空间关系的一致性;最后利用VB6.0+MO实现了该方法,并进行了大量的数据测试,取得了较好的效果。 In order to detect the spatial conflicts that rivers deviate from the valleys in the process of topographic database updating, a new algorithm using the vector projection method to quickly extract the valley lines related to the rivers is proposed. Based on the algorithm, a method to detect the inconsistency that rivers deviate from valleys is advanced. The above algorithm has been implemented by VB6.0 + MO, and achieved the better efficiency.
