Chamoli Disaster Pre-event 2-m DEM Composite: September 2015, Version 1
Listed in NASA Earthdata CMR
This data set contains a 2-m resolution DEM composite and auxiliary parameters over the Chamoli disaster area in Uttarakhand, India, where on 7 February 2021 a glacier burst led to a massive flood.
Description
This is the pre-event DEM constructed from monoscopic Maxar/DigitalGlobe WorldView-1 and WorldView-2 images collected in September 2015. A post-event DEM is available as a separate data set (Chamoli Disaster Post-event 2-m DEM Composite (February 10-11, 2021) and Difference Map, Version 1
