摘要
讨论了DEM的矢量数据类型,即等高线下的DEM数据生产与建库的基本问题,阐述了DEM数据生产方面的问题及其解决办法和建库中的问题及处理方法,并介绍了其简单的应用。
In this paper, we discussed vector data types of DEM which was the basic issue of data generation and database creation of DEM using contour lines. Also we analyzed problems as well as countermeasures on data gen- eration and database creation of DEM. At last, we made brief introduction on application.
