| Abstract: | Dynamic monitoring of Nanjing city extension was conducted by using the technology of remote sensing and GIS which include pseudo color composite based on principal components analysis,integrated processing of subtraction and quotient,IHS fusion and the analysis of buffer.Full use of the information of multi spectral data of landsat TM and SPOT panchromatic by operation was made.It was a valuable study on fulfilling computer automatic classification by taking advantage of multi source and multi phase remotely sensed data.It was found that the direction of Nanjing city extension is similar to the direction of road building by technology of GIS.The results of the study will provide references in directing layout of Nannjing City. |
