Chamoli Disaster Post-event 2-m DEM Composite (February 10-11, 2021) and Difference Map, Version 1 (HMA2_CPOST)
Data set:
HMA2_CPOST

Overview

This data set contains 2-m resolution DEM composites and a DEM difference map over the Chamoli disaster area in Uttarakhand, India, where on 7 February 2021 a glacier burst led to a massive flood. These post-event DEMs were constructed from monoscopic Maxar/DigitalGlobe WorldView-2, WorldView-3, and GeoEye-1 images acquired on 10 February 2021 and 11 February 2021, and one DEM was generated from Pléiades-HR1B in-track stereo images acquired on 10 February 2021. The DEM difference map was created from the September 2015 weighted-mean DEM composite and the 10-11 February 2021 weighted-mean DEM composite. The September 2015 pre-event DEM is available as a separate data set (https://nsidc.org/data/HMA2_CPRE).
