This study proposes the methodology of distinguishing the snow coverage area on mountains using terrestrial photography images. The pixel value of snow on the mountains in the image changes due to the effect of the slope condition. In the mountain slope condition, pixel value is lower by the effect of shadow. This paper, how to distinguish snow coverage for every slope conditions is considered, and it examined the distinction methodology of not being subject to the effect of shadow conditions. Snow coverage area distinguish accuracy in the terrestrial photography image is improved by the proposing methodology as compared to conventional methodology.
