Abstract: This paper analyzes the features of the spatial data and difficulties and shortages of traditional methods in clustering analysis of spatial data. A novel spatial data clustering method based on improved evolutionary algorithm, called SDCEA is proposed. It effectively solves the main problems in clustering analysis of spatial data and enhances the flexibility and efficiency of the clustering analysis. Numerical experiments show that SDCEA has better performance.

Key words: spatial data, data mining, evolutionary algorithm, clustering
