The paper is mainly about the application of IKONOS image in dynamically monitoring land use changing. A comprehensive approach is proved through analyzing the result and comparing with other results with ordinary approaches. The approach is that IKONOS and SPOT images are performed PCA after they are overlaid directly at first, then suitable principle components are picked to compose a pseudo color image in order to get abnormal spectral image which will highlight the changing information. The approach does not only remain the diversify information of the images, but also highlights the changing information. The application potential of IKONOS imagery is demonstrated as well.
