4. CONCLUSION
As a result of this research work, we learned that MODIS snow
products are easy to use and suitable for seasonal periods for
many years of snow cover (figure 2,3 and table 2). There is a
need for comparison study of the data before 2006 and after
2006. Landsat satellite information has a good distance
resolution and suitable use in detail research (figure 5). We
performed glaciers change detection analysis by using different
satellite data. From the results glacier area is decreasing from
both satellite data Landsat and MODIS. Future studies should
be focused not only satellite and ground truth data but should
also take analysis with synergy of climate data. There is need to
use of Radar data for snow thickness in the study area. This is
important information to resolve the pure water resource and the
balance between glaciers and snow coverage.
