Özet

In this paper, we investigate the radiance and reflectance values of the shadow regions in hyperspectral data, and their relation to the sky-view factors. For this purpose, first, we find the shadow regions using LiDAR data. Then, we compute the sky-view factors from LiDAR data. Upon investigating the reflectance and radiance values in comparison to the physical radiance model, we found that the sky-view factors are not as dominant as the photons reflected from the objects surronding the shadow region.
