| Abstract: | The TM remote sensing image can gain rich ground information,and therefore it is suitable for macroscopic monitoring in a large area.In the present study,the lamination classification method was used to extract the information on the land utilization from the area of Jiangning,Nanjing,and the changed information chart of the land utilization was obtained.Then the decision tree classification,the maximum likelihood method in the surveillance classification in practice and the precision comparison in the land utilization were discussed.Besides,the comparative analysis of the classified result chart and the analysis of the reasons for the changes in this region were also made with the help of the GIS spatial analysis. |
