Abstract
A bidirectional reflectance factor (BRF) model for urban areas for pixel si zes of more than 500 in x 500 in is developed. Possible applications includ e albedo calculation, improvement of classification, and change detection a lgorithms, simulated global BRF maps, and refinement of atmospheric correct ion algorithms. The model combines the BRF effects at several scales (stree t grid, intermediate-sized objects, and microscale). We present modeling re sults as well as a comparison with measured data. The basic features of the urban BRF are the hotspot and the independence of its shape from wavelengt h in the range 450 nm less than or equal to lambda less than or equal to 23 00 nm. An analytical function that approximates the model is proposed for e asy implementation and fast computation.
