The glacier extraction based on ASTER data

Abstract

We use high resolution image of ASTER to extract glacier, during the extraction, based on the methods of glacier extraction before, we make up a set of glacier extraction work flow combined with the research area and research data. As a result, it is proved that the accuracy of the glacier extraction is high, and achieve the need of the research, on the other hand, we research the debris classification of glacier tongue, also can get good result at last, we sum up the method and bring forward some new idea.
