Datasets description

The ice lake data in the Irrawaddy River Basin was collected based on ETM remote sensing images around 2005, referencing high-resolution images such as Spot and GeoEye-1. The dataset consists of 100000 basin boundaries, ice lakes, and river spatial and attribute data in the Irrawaddy River Basin, including the following files: Irrawaddy_ Boundary, Irrawaddy_ Glacial_ Lakes, Irrawaddy_ 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
