Abstract  

The three kinds of methods, such as training sites Supervised Classification (SC), Digital Numbers (DNs) statistics and Normalized Difference Snow Index ( NDSI) have been used to map snow cover distribution and then to calculate snow cover area. In this study, the remote sensing data sets from Landsat TM, Moderate Resolution Imaging Spectroradiometer(MODIS) and NOAA/AVHRR were selected to utilize for mapping snow cover since these images are most current remote sensing data to be
