This report was an effort for compilation of the research that had been held in the past in the field of glaciology using remote sensing as a technique. For this purpose, results of different research papers and projects in the chronological order have been discussed and a debate on the comparisons is presented. On the basis of thorough literature review, normalized difference snow index (NDSI) has been identified as a quick way to assess snow and glacial extent in the study area. Satellite data captured through Landsat MSS, TM and ETM+ in 1977-79, 1989-1992 and 1999-2001...

In supervised classification of remotely sensed imagery the analysts require a plenty of time for generating the representative signatures of the possible land-cover classes present in the image. Although the notion of picking a large number of input signatures leads to more efficient results but in most of the situations the time is an important factor. To save the lavish time, besides to obtain the reliable results, is the requirement of most of the analysts. In this study the results of supervised classification are used as reference for checking the reliability of the results obtained...
