资源简介：
The centerlines and maximum lengths of global mountain glaciers were extracted using an automatic extraction algorithm based on the latest global glacier inventory data, digital elevation model (DEM) data, and European allocation theory. In total, 198,137 glacier centerlines were generated, accounting for 99.74% of the total input glaciers and 91.52% of the RGI v6.0. The accuracy of glacier centerlines was 89.68%. A dataset containing 17 sub-datasets was generated through the above work, including two basic input datasets (Input glacier outlines and global glacier DEMs), two key result datasets (Global glacier centerlines and global glacier maximum lengths), four process datasets, six derived result datasets, and three supplementary datasets.
