Analysis of Glacio-Morphological Features by Remote Sensing Techniques

Glaciers are widely recognised to be sensitive climatic indicators and serve as a thermometer. The study of glacier dynamics is intimately related to the complex mountain-climate system and integrates with climatic effects spatially and temporally. However, the regular monitoring of glaciated terrains becomes difficult because of their inaccessibility and hindrance in collection of data through field methods. Thus, Remote Sensing and GIS serve as a useful technique to catalogue the changes in the glacier and understanding the climate change phenomenon. The results in this study show that satellite data can be used for extracting the quantitative and qualitative parameters of glaciers. The analysis of satellite imageries has led to the identification of various geomorphological features, consequently revealing the global climate change scenario and its long-term implications.
