摘要
等高线的精准描绘是地图绘制的关键问题。本文针对地图生产中等高线与高程注记点,研究可能出现的矛盾类型,引入基于等高线和高程注记点的不规则三角网检查方法与放射检查方法,以期为生产实践提供参考。基于ArcEngine组件库和C#语言,开发了等高线质量检查程序,并用实例数据对其检查结果的准确度进行了验证。研究结果表明:等高线节点构建不规则三角网进行点线矛盾的检查方法具有较高的精度,可满足项目生产需求。
Accurate and vivid depiction of contour lines is a key issue in map drawing.This paper focused on potential types of inconsistencies that may arise between contour lines and elevation annotation points during map production,and introduced an irregular triangulation network inspection method and a radiating inspection method based on both contour lines and elevation annotation points,in order to provide practical guidance for production workflows.Leveraging the ArcEngine component library and the C#programming language,a contour quality inspection software was developed,with its accuracy validated using real sample data.The findings indicate that the construction of an irregular triangulation network using contour line nodes effectively detects point-line inconsistencies with a high degree of precision,meeting the requirements of project production.
