Snow cover area is a very critical parameter for hydrologic cycle of the Earth. Furthermore, it will be a key factor for the effect of the climate change. Most research on estimating snow cover area is binary: pixels are verified either "snow" or "not snow". Most pixels, however, are mixed with snow, vegetation, soil, rock or water.

Topography and its derivatives (altitude, slope and aspect) have an effect on satellite-measured radiances. For mountainous areas the sun zenith and azimuth angles, as well as direction of observation relative to these are more limiting factors. In this paper four topographic normalization methods were used to correct the reflectance values of medium ...
