摘要：Detection and determination of ice and snow characteristics using remote sensing data is a new method in obtaining hydrology parameters. In order to determine these characteristics the numbers of meteorological stations are not enough in the glacier and mountain regions. We suggest using remotely sensing data for removing these deficiencies. Snow is distinguished more than other objects in the land by its different reflectance. But snow and clouds have similar reflectance, therefore MIR bands are used to distinguish them. In this paper , the methods of extraction snow cover area, new snow, compressed snow from optical images are described. In this study we use Landsat and IRS_LISS (III) images
