Copernicus DEM GLO-30 / GLO-90#

copernicus-dem · theme terrain · live

Global 30 m and 90 m digital surface model from the Copernicus DEM (WorldDEM heritage: TanDEM-X X-band InSAR, 2011-2015): the 2021 release on the Planetary Computer and Earth Search, the 2023_1 release on OpenTopography and the 2024_1 release on Earth Engine. Elevations are referenced to the EGM2008 geoid. The default DEM here because it is the most recent global model with the fewest voids; see esd.terrain.dem.compare() for the alternatives.

import easysnowdata as esd

aoi = (-121.94, 46.72, -121.54, 46.99)   # Mount Rainier
dem_da = esd.terrain.dem.load(aoi)

No account needed for the default route

source="planetary-computer" is open. source="gee" needs earthengine — see the credentials page.
