| Abstract: | The codification method based on the theory of the binary tree is able to locate any section of drainage net work directly and operate the topological relationship effectively.In this study,firstly,the basic method of extracting river channel network of watershed based on DEM data is discussed.Then,simulated river based on binary encoding rules is used to complete the classification of river network coding.The experiment achieves good results. |
