Global Land Ice Measurements from Space (GLIMS) is
an international initiative with the goal of repeatedly surveying
the world's estimated 200,000 glaciers.
The project seeks
to create a globally comprehensive inventory of land ice, including
measurements of glacier area, geometry, surface velocity, and
snow line elevation. To perform these analyses, the GLIMS project
uses satellite data, primarily from the Advanced Spaceborne Thermal
Emission and Reflection Radiometer (ASTER) and the Landsat Enhanced
Thematic Mapper Plus (ETM+), as well as historical information
derived from maps and aerial photographs.
Each feature in this dataset is a polygonal boundary of a glacier at the
time of analysis. A few glacier IDs have hundreds of distinct rows over
time.
This dataset is a snapshot of the inventory of glacier boundaries as of
June 7, 2023, providing over 1,100,000 rows.
