A review of multi-angle remote sensing research in china

Multi-angle remote sensing is proposed on the anisotropy characteristic of ground objects. Compared with the traditional unidirectional remote sensing, it is provided with the capability of obtaining 3D structure of ground objects and represents the new aspect of quantitative remote sensing. This paper introduced the latest achievements in multi-angle remote sensing in China. Firstly, some field and laboratory BRDF experiments for both vegetated and non-vegetated surfaces and major goniometry laboratories in China were introduced. Furthermore, this paper briefly reviewed different BRDF models and their applications in China, including the applications in vegetation canopy, rock et al. In this part, Thermal BRDF models and field measurements in thermal BRDF data were also discussed here. What is more, some key questions in BRDF model research were discussed. Finally, the present difficulties and future prospects of multi-angle remote sensing are analyzed.
