Reflectance in terms of pixel value based on LANDSAT TM seven-band data set of the Pho Chu area of Bhutan.
Red lines—clean glaciers and fresh snow (A); black lines—clouds (B); green lines—old snow/glaciers (C); maroon
lines—debris covered glacier (D); blue lines—clean/melted (E) and silty and/or partly frozen water (lake/river) (F)
