AutoCAD R14环境下的地形图矢量化

Topographical Digitization on the Condition of AutoCAD R14

在测绘领域 ,数字地形图的需求越来越广。传统的地形图大都是描绘在纸张、薄膜、复照底片和涤沦胶片等介质上 ,即模拟图。随着计算机和电子测绘仪器的广泛普及 ,使数字地形图的实现得到迅猛发展。笔者采用VisualLisp语言 ,利用AutoCADR1 4二次开发的程序 。

With the rapid development of science and technology,the demand of digital information and the field of application is widerly required.In the realm of surveying,the requirement of digital topography is more numerous than past.The paper discusses a way of by using Lisp language under the system of AutoCAD R14 to make a further exploration and to make the shift form simulated graph to digital graph.
