| 摘 要： | 基于等高线的三维真实感地形系统,首先把等高线地形图扫描进计算机,然后利用ERSI公司的GIS软件Arc/Info跟踪等高线生成矢量化的等高线数据,并根据得到的数据建立三维规则数据场生成三维地形模型。最后利用VC++6.0编程工具和OpenGL编程接口生成具有真实感的三维地形。实践证明该方法简单、实用。

| Abstract: | The system of 3D relief maps based on contour maps,firstly scans the contour maps into computer,secondly follows contour lines using GIS software of ERSI company-Arc/info to get vector contours and builds 3D regular data field based on digital contours to get 3D terrain model,finally visualizes 3D relief maps via Visual C++6.0 programming tools and OpenGL application programme interface of 3D graph visualization.It proved that this means of building 3D relief maps based on contour maps is simple and practical |
