二向反射模型在土地覆被制图中的应用
Application of BRDF model in land cover mapping
摘要
Abstract
The reflection heterogeneity of vegetation can reflect the structural and spectral characteristics of vegetation,and therefore it can help to identify vegetation more effectively.Misr multi-angle observation data has been explored in the sutdy of the lower Tarim River.Meanwhile,the kernel driven and RPV model inversion is used to obtain information of surface BRDF,and SVM method is used to study the land use and the cover of classification by the combination of MISR nadir reflectance data and BRDF information.By comparative analysis of the effect of the BRDF of the classification results,the findings are as following:①BRDF information can provide additional information for the land cover mapping in the semi-arid area and improve the accuracy of the mapping.②Both the kernel driven model and the RPV model can simulate the surface reflection in the study area.③After using BRDF,the identification accuracy of grassland and forest land increased obviously.关键词
