Due to the lack of support on the high resolution image in short time, the land-cover change detection is always applied on the multi-temporal remote sensed images with coarse resolution. They contain a large number of mixed pixels, which can seriously limit the utility of change detection. Pixel unmixing (PU) can be applied to improve this situation through deriving the abundances and generating...
Vegetation includes all plant communities that cover the earth surface. Vegetation coverage is the most important index to scale the status of the vegetation of the region, so the vegetation is the composition and the function body of ecological system. Vegetation coverage in different land use types of Miyun reservoir watershed were calculated based on remote sensing images (Landsat 5 TM images)...
Water plays an important role in the growth of vegetation. The research on vegetation water content is necessary to monitor the degree of drought, flood and ecological security. When we observe the large area and need rapidly response, remote sensing has advantage in monitoring and estimating the vegetation water content. NOAA-AVHRR data is usually used by original process of estimating on vegetation...
