The global desert coverage has been rapidly expanding due to the reasons such as climate change and uncontrolled human activities. Thus, the importance of the observation tool not only for the growth of desert but also for the sandy dune activity has been recently noticed. In this study, we developed the monitoring methods of sand dune field by the Multi angle imaging Spectro Radiometer (MISR). Normalized Difference Angular Index (NADI) extraction was proposed as the main idea tracing the sandy desert because of its obvious correlation with the local roughness properties of the sandy dunes fields. For the test areas in Kubuchi and Badein deserts in northwest China, the spatial and temporal transitions were well identified employing the scheme based on MISR NDAI. The algorithms to measure the magnitude of sand dune migration will be further developed.
