摘要：Albedo can be simulated through constructing the albedo calculation model in the three-dimensional urban structure. The paper utilizes the street structure BRDF model to simulate the BRDF in the urban areas. Based on the statistical methods, we determine the best close to the actual city building height, width and density and propose a new method to calculate the vegetation coverage which is an important parameter in simulating the BRDF in the study area. Based above, we simulate the reflectance in the actual area in the NIR band using multi-angular data. The simulated results compared with the MODIS surface reflectance product data in the same urban areas and the same band. The results show that the relative error is less than 6% with the angular change. It will be helpful to further study the BRDF in the urban area.
