The Afghanistan Ice Lake data was collected based on ETM remote sensing images from 2005, referencing high-resolution images such as Spot and GeoEye-1. The dataset includes spatial and attribute data of 100000 basin boundaries, ice lakes, and rivers in Afghanistan, including the following files: Afghanistan_ Boundary, Afghanistan_ Glacial_ Lakes, Afghanistan_ Rivers. In the attributes of glacial lakes, the distance from glaciers to glacial lakes (dist2gr) may not correspond to glaciers, with a value of 0; Glacier lake orientation (gl_orient) Some lakes are not oriented, with a value of 0.
On a scale of 1:100000
Dimension:
Gl_ Length: kilometers; Gl_ Area (Ice Lake Area): square kilometers; Dist2Gr (distance from glacial lake to glacier): kilometers
