Abstract Current GISs lack efficient management and analysis functions for coastline dynamic changes for coastline is a special line object. In order to resolve this problem, the concept of stationary points is introduced, and a coastline analysis method is put forward based on current GISs. Through analyzing stationary points, the dynamic changes of coastal siltation or erosion can be obtained. Thus, the analysis of coastline changes can be accomplished automatically. In this paper, experimental analysis is performed on the real coastline data of Yellow River Mouth, which turns out that this dynamic analysis method is valid.
