GLIMS (Global Land Ice Measurements from
Space) is an initiative designed to monitor the world's
glaciers primarily using data from optical satellite
instruments. Read about the main features
of the GLIMS Glacier Database.

The Randolph Glacier
Inventory (RGI) is a global inventory of glacier outlines. It is
supplemental to the GLIMS database, and is a map of glaciers for one
time and a collection of useful attributes.
Over 60 institutions across the globe are involved in GLIMS. General
coordination, technical development, and data management are done
NSIDC in Boulder, Colorado, USA.
"Glim" is an archaic Scottish term that means "a passing look; a
glimpse; as much as is seen at a glance." In a future historical
perspective, we may well look back on GLIMS and other early-21st Century remote-sensing of Earth's
glaciers as a glim of a passing or changing phenomenon.
