地形图中等高线与高程点矛盾检查方法探讨

Discussion on the Method of Checking Contradiction between Contour and Elevation of Topographic Map

系统地介绍了地形图数据中,以红、黄、青、蓝、紫5种颜色赋予一组等高线由低到高的色值,形成高程谱,结合高程点同区间的颜色,快速准确地判定点线是否矛盾,杜绝高程点和等高线间点线矛盾错误的方法。

In this paper,we introduce the topographical data give a group of contour lines from low to high color in five colors:red,yellow,indigo,and blue and purple,forming a height spectrum,combining the color of the same interval at the elevation point.Quickly and accurately determine whether the point line is contradictory and eliminate the point line contradiction error.
