摘要
提出一种由等高线地形图生成三维地形图的方法.首先对等高线地形图进行数字化处理,获取离散点高程数据,并采用克里金插值法获取数字高程模型;然后以Visual Studio 2008为开发平台、VTK(Visualization Toolkit)为工具生成三维地形;最后用实例验证了所提方法的有效性.
The paper presents a method of generating three-dimension terrain by contour map.Firstly,elevation data of discrete points and digital elevation model are obtained through digital processing of contour map and Kriging interpolation method respectively.Secondly,the three-dimensional terrain is produced with the adoption of Visual Studio2008 as the development platform and VTK as a tool.Finaly,an experiment is employed to prove the method discussed in this article is workable.
