Abstract: According to the defects of current bend identification methods, this paper proposes a multi-way tree structure for representation of curve bends. The method uses curve axis to identify curve bends. Bends which exist in different direction and different range of curve are extracted hierarchically by a recursive way and a multi-way tree of bends is generated according to extraction results. Finally, the multi-way tree of bends was used in the experiment of line generalization and verified its effectiveness.

Key words: curve bends, cartographic generalization, multi-way trees, curve morphology
