分水线

DEM不仅表达了地面高程的空间分布，而且据此可以自动生成流域的水系和分水线、自动提取地形坡度和其它地貌参数。

Not only because DEM express spatial distribution of ground elevation , but also because drainage networks and watershed boundary are generated and topographical gradient and other hypsographic parameters are extracted automatically from DEM .
