Research on the Method of the Auto—Generalization of Contour Based on the Algorithm of Multi-resolution Simplification

This paper deals with the research on the auto-generalization of contour based on the algorithm of multi-resolution DEM tested in an experiment.The TIN was constructed based on the discrete regional point data and the contour was retraced and created after the TIN scale had changed by utilizing the algorithm of the most independent points aggregation.Consequently the autogeneralization was realized.This method is characterized by the advantages of simple algorithm,high practicability,as well as the ability to keep the original terrain.The research in this paper is the exploration and practice of a new method in the field of generalization,which can help to realize generalization.It proves to be an innovative way in the realization of relief form generalization.
