摘要
通过利用ArcView和Erdas软件分别进行了矢量与栅格文件的处理,讨论并实现了从 DEM获取各级水系的长度、数目、密度及流域面积等参数,同时计算了水系的分形维数。为进行更进一步的水系分析奠定了基础。
How to obtain all levels parameter like as water system’s length、amount、density and drainage area from Digital Elevation Model and to accoun water system’s dimension are argued and implemented by using two software of ArcView and Erdas to deal with vector and case document.It establishes more foundation for water system’s analyse.
