A desertification monitoring model was constructed and applied in a region nearby Gaotai Country, China, where undergoing a typical desertification process. First, the surface albedo and vegetation index were retrieved. And by statistical regression analysis, the quantitative relationship between albedo and NDVI of different desertification land was determined, and found they have good correlation...
In this study, 9 quantitative indices of remote sensing were established by using the spectrum information of Landsat TM image in 2006 and the topographical information of DEMs with the techniques of RS and GIS. Then, these indices were used to establish a discriminated function based on the stepwise discriminant analysis of spatial statistics in support of SPSS software. The wetland, grassland, river,...
Remote sensing of vegetation is developing into a highly quantitative science. 6S atmospheric correction model based on radiative transfer theory, with a definite physical meaning, but it provided a limited number of patterns which are difficult to reasonably describe atmospheric conditions in a specific study area, therefore, in the absence of measured data, it is necessary to select or estimate...
