This data set is 1:100000 cataloging data of glaciers in Ganges River Basin in 2005. Based on the geometric correction of multi landscape Landsat remote sensing images in 2005, the dataset is digitized according to 100000 precision, including spatial vector data and attribute data.
Ganga_ Glacier attribute field: Field 1: glims_ ID glacier code Data type: text (14) Field 2: area area Data type: double (13,3) Field 3: longitude Data type: double (8,6) Latitude: 4 Data type: double (8,6) Field 5: datasource image type Data type: text (7) Field 6: DS_ Date Data type: text (4)

By using remote sensing software such as GIS and envi, the required images are precisely corrected to ensure that the error of adjacent images is less than one pixel. After digitization, spatial data and attribute data are extracted, sorted and edited in strict accordance with 100000 scale.
The data quality is good, and the data of planning map, map and remote sensing image are refined and corrected
