The conventional waterway network coding system is mainly based on the digital coding which describes the topological relation of waterway network,but the basic information content of waterway itself is less.This method is easy to computer storage,but not intuitive.In order to solve this problem,different types of waterway network codes are summarized by classification method,and a hybrid texture-number coding system is proposed.This system encodes the waterway network by combining words and numbers,which has the characteristics of high identification,convenience,high efficiency and strong applicability,and effectively solves the problem that the plane position relation and basic waterway information cannot be integrated in the process of waterway network coding.
