摘要	Automated glacier mapping from satellite multispectral image data is very difficult because of the similar spectral characters of lateral and terminal moraine with that of neighbor rock. Paul has developed a method which integrate ASTER multispectral image with digital elevation model to map two debris-covered glaciers in Alps. However, there are some problems when using in many mountain glaciers in West of China. The critical slopes which identify the debris-covered tongue from rocks were tested at first, which reveals that there isn't a unique critical slope for all glaciers. Vectors from China Glacier Inventory were used to expand and shrinkage which acting as a mask. A Temperature Index image was calculated by one window algorithm from Landsat band 6 and NDVI. The method combines the advantage of Paul's method with the mask and Temperature Index. Most of the processing can be done automatically. It was applied to Keqikaer debris-covered glacier, west Tianshan Mountain, China.
