NASADEM (SRTM reprocessed)#

nasadem · theme terrain · no data

NASA’s 2020 reprocessing of the February 2000 SRTM C-band radar mission: 30 m, 60°N to 56°S, voids filled with ASTER GDEM and other sources, referenced to the EGM96 geoid. The same surface as SRTM GL1 with better geolocation and fewer voids, and the credential-free way to get an SRTM-heritage DEM.

import easysnowdata as esd

aoi = (-121.94, 46.72, -121.54, 46.99)   # Mount Rainier
data = 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.
