Glacier facies characterisation in transboundary West Sikkim Himalaya from TerraSAR-X; GLCM based classification approach

The proposed facies classification approach uses three features of the GLCM with multitemporal X-band SAR data TerraSAR-X combined k-means clustering. This was tested on 15 transboundary Himalayan glaciers. They were classified into six namely debris, dry snow, wet bare ice, percolation zone 1 and 2 covered areas for these classes are 20.56%, 12.50%, 20.26%, 13.16%, 25.49% 8.03% total area respectively. After classification, signature validated using benchmark outline East Rathong glacier, India. accuracy achieved is 89.56% negligible variance kappa 0.87.
