High-resolution (2 metre) digital elevation models of difference showing surface change following the Chamoli ice-debris flow, India, February 2021
Description
These data are digital elevation models (DEMs) of difference (DoD). They are a geospatial dataset created in raster (.tif) format and quantify vertical (z) topographic change between two dates. 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 also supported numerical modelling using CAESAR-Lisflood (see related data collection). They are most commonly imported into GIS software, where they can be analysed or support other forms of geospatial analysis.
