(2020). Glacial lakes in the Koshi, Gandaki, and Karnali river basins of Nepal, the Tibet Autonomous Region of China, and India [Data set]. ICIMOD. https://doi.org/10.26066/RDS.1971946 The data on glacial lakes in 2015 were derived through a semi-automatic method using Landsat imagery from 2015 to 2016. The Normalized Difference Water Index threshold value was used for classification. Further, the lake boundary was revised or manually updated by incorporating those lakes that were missed because of atmospheric and physical processes such as being frozen, covered under snow, or obstructed by shadows and clouds. The mapped glacial lakes were validated and modified where necessary by overlaying the Landsat imagery over previous inventory datasets. They were also cross-checked with high-resolution Google Earth imagery. The attributes of glacial lakes were derived from SRTM DEM, and the data were projected in the WGS UTM projection system. This dataset was prepared to support the Green Climate Fund project proposal formulated by UNDP Nepal. The dataset provides the status of glacial lakes in 2015 in three main river basins (Koshi, Gandaki, and Karnali, including Mahakali) that drain into Nepal. It is useful for researchers, scientists, and infrastructure developers, and policymakers for glacial water resource management, climate change impact studies, and glacial hazard risk reduction and mitigation. http://rds.icimod.org:8080/geonetwork/srv/api/records/777e6cb6-c2db-47ab-852c-48bd0f24a158/attachments/GLDistribution.png http://rds.icimod.org:8080/geonetwork/srv/api/records/777e6cb6-c2db-47ab-852c-48bd0f24a158/attachments/GLDistribution.jpg http://rds.icimod.org:8080/geonetwork/srv/api/records/777e6cb6-c2db-47ab-852c-48bd0f24a158/attachments/GLDistribution.png http://rds.icimod.org:8080/geonetwork/srv/api/records/777e6cb6-c2db-47ab-852c-48bd0f24a158/attachments/GLDistribution.jpg Glacial lakes in the Koshi, Gandaki, and Karnali river basins of Nepal, the Tibet Autonomous Region of China, and India Glacial Lake Potential dangerous glacial lakes GLOF Cryosphere Nepal China India Creative Commons Attribution 4.0 International (CC BY 4.0) eng geoscientificInformation 80.0726 88.7198 27.4357 30.622 2015-09-01 2016-12-12 ICIMOD 977-1-5275222 metadata@icimod.org https://lib.icimod.org/record/34905 WWW:LINK-1.0-http--link HimalDoc
