The tools require the following gridded\ndatasets: (1) atmospherically-corrected surface reflectance,\n(2) a digital elevation model (DEM), and (3) satellite and\nsolar azimuth and zenith angles. The package includes tools\nfor: image pre-processing (crop grids to a specified extent,\nproject grids with different coordinate systems, and convert\ndata from integer to floating point); convert nadir satellite\nobservations to off-nadir values using view-angle corrections;\ndetect and mask topographic shadows; automatic discrimination\nof snow and ice surfaces; anisotropic correction of reflected\nradiation of glacier snow and ice using empirical\nparameterizations of the bidirectional reflectance distribution\nfunction (BRDF); topographic correction; and\nnarrow-to-broadband albedo
