中文摘要: |
DLG是一种将地理要素分层存储的矢量数据集,其包含了空间信息和属性信息,利用其属性信息,将空间展布的各要素以符号化的形式表达出来,形成传统地形图以供使用者判读、应用,将会大大提升传统地形图的生产成本、成图周期,弥补传统地形图现势性差的弱点。笔者借助ArcMap平台,通过投影转换、样式符号制作及要素符号化、符号标注、制图综合及图面整饰一系列过程,详细介绍了从1∶5万DLG数据库至传统地形图的转换过程,并总结出了转换过程中的重点和难点工作,同时提出了利用mxd文件模板采用修改数据源的方法可实现同比例尺其他图幅的快速转换,提高工作效率。 |
英文摘要: |
DLG is a vector data set that hierarchically stores geographic featuresIt contains spatial information and attribute informationUsing its attribute information,the spatially distributed elements are expressed in a symbolized form to form traditional terrainFigures for users to read and applyWith the help of ArcMap platform,the author introduces the conversion process from 1∶50,000 DLG database to traditional topographic map through a series of processes such as projection conversion,style symbol production and feature symbolization,symbol annotation,cartographic synthesis and surface decorationSummarized the key and difficult work in the conversion process,and proposed the use of the mxd file template to modify the data source method can achieve rapid conversion of other maps of the same scale,improve work efficiency |
