摘要
地形图是进行城乡规划、土地利用总体规划的重要依据,对于全面加强土地管理具有重要作用。但是,使用传统方法进行地形图缩编费时费力,本文以某市1∶500到1∶2 000地形图缩编为例,充分利用Auto CAD的二次开发功能、FME Converter平台的数据格式转换和Arc GIS的制图综合工具,采用半自动缩编的方法,提高缩编的工作效率,提供了一种智能化缩编方法的新思路,并介绍地形图中各要素的关键编绘技术及其处理技巧。
Topographic map which plays a significant role in the management of land use is the basic reference to urban planning and general land use planning at the present time. While it costs a great deal of time and money on topographic map generalization in traditional ways. In this paper,a new method using Auto CAD and Arc GIS to generalize topographic map from large scale 1∶ 500 to 1∶ 2 000 was proposed,and the key skills in dealing with generalization of topographic map were shown in detail. The method could improve the generalization efficiency significantly; therefore,it showed theoretical and practical importance on topographic map generalization.
