摘　　要：利用1∶2 000比例尺地形图进行缩编制作1∶5 000比例尺地形图,是充分利用现有资源、节约成本、缩短成图周期的有效方法。由于大比例尺地形图负载量多于小比例尺地形图,为了使缩编后图面清晰易读,反映本地区地理特征和区域特征,须舍弃部分次要、不必要的要素,同时根据区域特点和用图需求对其中要素进行综合取舍。研究利用基于Auto CAD平台二次开发软件实现部分自动化缩编,在地形图拼接、改变符号大小、删除多余要素、要素综合取舍、高程点抽稀等方面均实现了自动化,提高了50%的工作效率。Using the topographic map with scale of 1∶2000 to compile the topographic map with scale of 1∶5 000 is an efficient way to make full use of existing resources,save costs,and shorten the period of drawing.Due to the large scale topographic map loads more information than the small scale topographic one,in order to make the small scale topographic map easy to read and reflect the local geographical features and regional characteristics,it is necessary to abandon some minor,unnecessary elements,and then make choice of the elements comprehensively according to the regional characteristics and graph demand.The secondary development program based on the Auto CAD platform is studied and used to realize partly automation of generalization, and the automation of topographic map matching,symbol size change,deletion of redundant elements,comprehensive choice of elements,elevation point sparsing and other aspects are realized,thus work efficiency is increased by 50%.
