New Approach for Snow Cover Detection through Spectral Pattern Recognition with MODIS Data

Figure 6

Error plots of preconstructed snow reflectance spectral libraries. (a)–(g) indicate solar zenith angle (SZA) classes, and lines with different colors and symbols indicate digital elevation model (DEM) classes. In each SZA class, different patterns of reflectance change by wavelength are apparent, especially in the visible wavelengths.
