摘要
制图综合是当前地图学家们关注的焦点问题和前沿问题,在地图中线状要素所占比重往往最高,因此它是制图综合的一个重要方面。本文分析了线状要素制图综合的特点及Arc/Info软件的综合功能,并在此基础上提出了基于Arc/Info解决线综合问题的策略;然后以土地利用专题图作为实验数据,给出其在Arc/Info中的实现算法,同时对不同的实现方法进行比较,最后分析实验结果。
Map generalization is one of the most concentrated focus and front problem for cartographers currently. Generalization for linear feature is an important aspect in map generalization because the proportion of linear feature is the highest in map. This paper analyzed the characteristics of generalization for linear feature and the comprehensive function of Arc/Info software. Then it put forward the solutions to resolve generalization for linear features. Taking land use thematic map as experiment data, it presented the realization algorithm in Arc/Info. It also compared the different realization methods and analyzed the experiment results.
