基于R2V与ArcGIS的地形图数字化与三维显示研究

Making Vector Data and 3D Display from Relief Map by R2V and ArcGIS

本文介绍一种基于R2V与ArcGIS软件对地形图进行矢量化和三维显示的方法,使得地形图的数字化和三维显示变得简便、快捷、易行。首先利用R2V软件对地形图中的等高线进行矢量化、编辑、赋高程值,然后导入ArcGIS软件中进行处理和三维显示。通过两者的结合使用,充分发挥两个软件的功能,实现优势互补,完成地形图的高效数字化和DEM的高效制作,为技术人员提供参考。

The method using R2V and ArcGIS software to scan and vector relief map and 3D display easily and quickly was introduced. Firstly, the contour line from relief map was vectored by R2V, the data were edited and added with the value of contour line and then input to ArcGIS to make geoprocessing and three-dimensional dis- play. The effective digitization of topographic map can be finished with the help of the integration of R2V and AreGIS, which contribute to the advantage compensation and provides references for technical staff.
