Based on TINs DEM, a new single-flow direction algorithm for topographic patterns extraction is proposed.
基于不规则三角网DEM，提出一种新的单流向地形特征自动提取算法。

After detailing the first of the nine flows, we can immediately turn them over to the design team, and spend time with them to see how well the singleflow guides their work.
在详述九个流的第一个之后，我们可以立即将它们转到设计团队，并花时间观察此单个流如何指导工作。
