| Abstract: | The application of remote sensing technology in 1990s has stepped into the stage of commerdalization and socialization all over the world. One of the spectacular development trends of remote sensing technilogy in 1990s is the microcomputer based image processing.In this study, the popular personal computer and the software IDRISI for processing the multibands of TM imagcs with principal component analysis (PCA) and colour space transformation (IHS) are used. The superiority of the combination of PCA transformation with IHS transformation are discussed. The purpose of this experimental study is to make it play a practical role in the microcomputer based image processing, investigation, inspection and research on regional resources and environment. |
