This dataset contains the contemporary glacier inventory of China, which was compiled totally based on Landsat TM/ETM+ imageries acquired around 2007. All the Landsat imageries were obtained from USGS websites (http://glovis.usgs.gov, and http://earthexplorer.usgs.gov). The glacier outlines in this dataset were semi- automatically extracted by widely used band ratio segmentation methods and improved by multi-rounds manual works.
In current version (V1.0), this dataset includes 42,359 glaciers with a total area of 42,938 km2, distributing in seven large exorheic river basins (i.e. Ertix River, Yellow River, Yangtze River, Mekong River, Salween River, Ganges River, and Brahmaputra River) and six inland basin systems (i.e. Hexi basins, Qadam basins, Tarim basins, Jungar basins, Turpan- Hami basins, and Tibetan Plateau interior basins). The dataset includes a set of attributes characterizing each glacier, includes GLIMS ID, drainage basin code, first glacier inventory ID, glacier area and perimeter, latitude and longitude of glacier central point, maximum, mean, minimum, and median area elevation in glacier-covered topographies, mean slope and aspect, primary and auxiliary data source, and date tag of the glacier. The glacier topographical parameters were calculated from SRTM V4 DEMs.
