| Abstract: | This paper introduced Bayes classifier, and presented a method for knowledge mining from GIS spatial database, used it to support image classification. Integrating geographic data, interpretation knowledge used by expert, a new method was proposed. In classification procedures, the associated geographic data are used as well as imagery, and knowledge is represented by rules. The method has been approved to be effective to improve the classification accuracy compared to the traditional method. Experiment approved it's a good classification method. |
