Datasets description

This data is collected from the the Yarlung Zangbo River basin ice lake data based on the ETM remote sensing image in 2005, referring to the high-resolution images such as Spot and GeoEye-1. The data set is the the Yarlung Zangbo River 100000 basin boundary, ice lake, river data space and attribute data, including the following files: Brahmaputra_ Boundary, Brahmaputra_ Glacial_ Lakes, Brahmaputra_ Rivers

Scale 1:100000

Ningxia_ City_ Point (urban settlement) attribute field

a. Name Explanation

Field 1: Basin_ Code (Basin Name) Data type: String (254) Field 2: gl_ COAD (Ice Lake Code) Data type: String (254) Field 3: Longitude Data type: String (254) Field 4: Longitude (Ice Lake Latitude) Data type: String (254) Field 5: altitude Data type: Number (19) Field 6: gl_ Area (Ice Lake Area) Data type: Number (19) Field 7: gl_ Length Data type: Number (19) Field 8: gl_ Class (Ice Lake Level) Data type: String (254) Field 9: datasource (image) Data type: String (254) Field 10: gl_ Orientation Data type: String (254) Field 11: dist2Gr (distance from glacial lake to glacier) Data type: Number (19) Field 12: Ds_ Date 1 (image time) Data type: Date (8)

B Dimension (unit of measurement)

Gl_ Length: kilometers; Gl_ Area (Ice Lake Area): square kilometers; Dist2Gr (distance from glacial lake to glacier): kilometers

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
