地形图的R2V矢量化与ArcView的三维显示

Vectorization of Topographic Map in R2V Software and 3D Display in ArcView Software

随着计算机技术的发展,地形图的计算处理变越来越迫切,也越来越易,介绍一种对扫描地形图矢量化的软件R2V的方法,使得地形图的矢量变得简便、快捷、易行.完成矢量化后,为了在三维显示的时,易于地形特征值坡度、坡向的提取建议导入地理信息系统软件如ArcView中创建数字高程模块(DEM)进行三维显示.同时以长岭岗林场为实例进行演示操作.

With the development of computer technology, using computer technology in topographic map processing becomes necessary and easy. In this paper Changlinggang forest farm was taken as an example and a method using R2V software to scan and vector topographic maps easily and quickly was introduced. To extract slope gradient and aspect of slope of topographic eigenvalues easily after vectorization in R2V software, the best way to 3D display was to create digital elevation model（DEM） in geographic information system software such as ArcView.
