Monitoring of glacier changes plays an important role within the Global Climate Observing System (GCOS) [ Haeberli et al. , 2000] and Landsat imagery has proven to be a useful tool for monitoring glacier changes over large and remote areas [ Aniya et al. , 1996; Li et al. , 1998]. An accurate glacier map can be obtained by simple segmentation of a ratio image from Thematic Mapper (TM) channels 4 and 5 [ Bayr et al. , 1994, Jacobs et al. , 1997; Paul, 2002] Individual glaciers were recently derived within a Geographic Information System (GIS) using a vector layer with glacier basin boundaries. Glacier changes were calculated and visualized by processing sequential images within a fully automated work flow.
