Abstract: Systematical clustering is a kind of typical clustering method of spatial analysis,applied widely in many fields. But because of the limitation of its own algorithm,many systematical clustering programs can't process the data efficiency. Aiming at several factors limited the running efficiency,this paper puts forward a reasonable data structure to optimize the computer program of systematical clustering based on the computer programming,which reduces the complexity of time and space and enhances the capability to deal with a great deal of spatial data. The case of application has proved that the optimized method is highly effective.

Key words: systematical clustering, algorithm optimization, data structure
