Main content

The Randolph Glacier Inventory (RGI) is a global data base of glacier outlines. It is intended for estimates of ice volume and glacier mass at regional and global scales. The data are organized into 19 large regions, with a shapefile provided for each region. The RGI is produced as part of the Global Land Ice Measurements from Space (GLIMS) initiative, a project to compile glacier information using remote sensing, primarily from optical instruments such as ASTER (Advanced Spaceborne Thermal Emission and reflection Radiometer).

Key Strengths

Key Strengths

One of the most comprehensive and up-to-date inventories of world glaciers; contains approximately 682,605 km^2 of glacier area

The glacier outlines can be combined with DEMs to give areas, area distributions and area-elevation distributions

Key Limitations

Key Limitations

Lacks glacier IDs and other metadata found in other inventories

Glaciers on the periphery of Greenland and Antarctica are included but it is sometimes ambiguous whether they are part of the ice sheets

Scaling glacier observations to contributions to sea level requires accounting for unobserved glaciers, as well as empirical or modeled relationships between a glacier's area and its volume, mass or mass balance
