Randolph Glacier Inventory (RGI)

A globally complete inventory of glacier outlines for monitoring the world's changing glaciers.

Data

The Randolph Glacier Inventory (RGI) is a comprehensive dataset providing outlines of glaciers worldwide, excluding ice sheets. It serves as a snapshot of global glaciers, primarily targeting the year 2000, and is crucial for large-scale analyses of glacier volume and climate response. The RGI is a subset of the broader GLIMS initiative.

EarthEnv-DEM90

Global, remote-sensing supported environmental layers for assessing status and trends in biodiversity, ecosystems, and climate.

Data

EarthEnv-DEM90 provides a nearly-global, void-free, 90m digital elevation model derived from fused ASTER and SRTM data. It offers continuous coverage for approximately 91% of the globe, supporting assessments of biodiversity, ecosystems, and climate.
