| Abstract: | This paper presents the preparatory work and work flow of remote sensing change detection. The change detection technique and its applications are also introduced. Varieties of useful methods of change detec- tion of recently years were summarized in this paper such as image differencing, image ratio method, principal component analysis, NDVI, post-classification comparison and so on. Has analyzed the important function of change detection in the fields of national land resources、forest-fire、sea and military. |
