Randolph Glacier Inventory (RGI)

The Randolph Glacier Inventory (RGI) is a globally complete dataset offering outlines of glaciers, excluding the Greenland and Antarctic ice sheets. It is a key component of the Global Land Ice Measurements from Space (GLIMS) initiative. While GLIMS is a multi-temporal database, the RGI focuses on providing a snapshot of the world’s glaciers, with a target date as close as possible to the year 2000, for glaciers larger than 0.01 km². The RGI's strength lies in its ability to handle large numbers of glaciers simultaneously, enabling estimations of glacier volumes and responses to climatic forcing at regional and global scales.
