The Himalayan ecosystems have characteristics land and vegetation distribution pattern owing to its varied complexities in topography, seasonality, changing climate and socioeconomic interventions. The comprehensive mapping of land and vegetation cover in the Himalayas has always been a great challenge to the cartographers and remote sensing scientists. The focus of this chapter is to demonstrate a practical approach to map and understand land and vegetation cover distribution, and their dynamics over interval of three decades using earth observation data. The study provides an insight to characterize the vegetation pattern across an elevation gradient using geospatial techniques in a test site of Kargil district in the Ladakh Union Territory, India. Two set of images during August-November 1975 and 2005 were used in classification that provided high classification accuracy of >90% (overall, and 0.86 kappa), as per field correspondence. This spatial analysis has indicated that LULC demonstrated significant changes during 1975-2005. It was observed that the barren lands and the snow cover areas together contributed to nearly 80% of the total area in 1975, whereas in 2005, they contributed to nearly 60% area of the district. Variation in elevation range owing to distribution of the vegetation classes was realized for the eastern and western aspects. The separation of classes with a sharp boundary between two adjoining classes is absolutely impossible in nature. Therefore, some
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
