Abstract
The Altun mountains is located in the northern edge of the Tibet Plateau. It is the boundary of the Tarim Basin and the Qaidam Basin, which is bounded by the Dajinshan pass and the upper reaches of the Qiemo River. Glaciers in the Altun Mountains are subcontinental glaciers and polar continental glaciers. The boundary and length are two vital parameters of one glacier, whose change can directly reflect its advance and retreat, and indirectly characterize the regional climate change. Based on the Landsat OLI images and SRTM DEM, the boundary and glacier length of glaciers in the Altun mountains in 2016 were obtained by means of manual visual interpretation and glacier centerline method. The dataset contains two parts: 1) glacier boundary vector data in the Altun Mountains in 2016; 2) glacier length vector data in the Altun Mountains in 2016. This dataset reflects the boundary and length of glaciers in the Altun Mountains in 2016 and can be used as the basic data of glacier change and regional climate change research.
