Abstract

This chapter highlights the scope and nature of research work done in the northwest Himalayan region using hyperspectral images and field measurements. Spectral signatures were collected for varying snow grain size, contamination, adjacency factors, and other ambient objects. The retrieval of snow parameters such as grain size, contamination, and spectral albedo using high-resolution imaging data at different wavelengths are discussed. Wavelengths 550, 1240, and 1660 nm are found to be useful measurements for discriminating different features ...
