High-resolution (2 metre) digital elevation models of landscape affected by the Chamoli ice-debris flow, India, February 2021

These data are digital elevation models which describe landscape topography. The data were created to support analysis of landscape change following the 7th February 2021 avalanche-debris flow in Chamoli District, Uttarakhand, India. The data were used as standalone datasets to support this analysis, but also supported numerical modelling using CAESAR-Lisflood (see data collection). The DEMs were created from CNES/Airbus Pléiades-HR stereo satellite imagery captured in along-track mode. They are a geospatial dataset created in raster (.tif) format. They are most commonly imported into GIS software, where they can be analysed or support other forms of geospatial analysis.

Statement
The DEMs were created from CNES/Airbus Pléiades-HR stereo satellite imagery captured in along-track mode on the dates provided in section 1.4 of the supporting documentation. To generate new DEMs at 2 m grid resolution we used a block matching algorithm implemented in the open-source NASA Ames Stereo Pipeline (version v2.6.2_post). We registered the new DEMs to an existing composite DEM dated to September 2015 using the demcoreg toolbox. We also clipped and re-aligned an existing post-event DEM dated 10 February 2021 to the same September 2015 DEM.
