摘要
介绍了利用地理信息系统软件ArcGIS 9.0来构建DEM的方法,并对生成的荆江分洪区DEM进行了坡度分析。DEM还可应用于区域规划、城镇规划和土地评估等工作中。实验证明,这种方法除了地形图的扫描外,其他过程都在ArcGIS 9.0软件中完成,不需要投入大量设备,成本低,速度快,容易更新,并可按工程的规模实时组织进行。
The method of constructing DEM using geographical information system software ArcGIS 9.0 was introduced, and the slope and aspect were analyzed of the DEM of the Jingjiang flood diversion district. The DEM can be applied to regional planning, town planning and soil evaluation etc. This method has many advantages, such as few facilities, low cost, rapid building, easy to update, and real-time organization according to the scope of project.
