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)...
Remote sensing has proved to be very useful in the investigation of vegetation and hydrological monitoring, especially when studying vast areas. In this paper, the complement between two optical remote sensing data (Landsat TM and NOAA- AVHRR) and a Digital Elevation Model (DEM) is used to estimate hydrological parameters based on derived surface reflectance. These parameters which are used in the...
The ERS-1/2 wind scatterometer (WSC) has a resolution cell of about 50 km but provides a high repetition rate (less than four days) and makes measurements at multiple incidence angles. In order to estimate effective surface reflectivity (related to soil moisture content) over bare soil using this instrument, an original methodology based on the integral equation model (IEM) is presented that takes...
