rgi-glaciers · theme boundaries · live

Global glacier outlines outside the ice sheets, per first-order region: RGI 7.0 glaciers and glacier complexes (2023), or RGI 6.0 (2017) for comparison with the literature built on it.

import easysnowdata as esd

aoi = (-121.94, 46.72, -121.54, 46.99)   # Mount Rainier
glaciers_gdf = esd.boundaries.glaciers.load(aoi)
