Title

Building, infrastructure, and river channel reaches in Chamoli district, India, following the ice-debris flow, February 2021

Abstract

These data are GIS shapefiles which contain geospatial information describing the location and condition of bridges, buildings and roads in Chamoli District, Uttarakhand, India, following the 7th February 2021 avalanche and debris flow hazard cascade (the so-called ‘Chamoli event’). The dataset also contains a GIS shapefile which contains polygon outlines supporting geomorphological analysis of change in river valleys between the avalanche source and the town of Joshimath. The latter is designed to be used in conjunction with the other data resources contained in this data collection. Full details about this dataset can be found at https://doi.org/10.5285/a763e254-c249-4934-b0fb-c3b808b37db6

Lineage

The data were created by manual digitisation of GIS shapefiles (polygons and polylines) in ArcGIS Pro software (version 2.8). Existing satellite imagery were used as the reference data. Satellite imagery supporting building and infrastructure mapping was obtained by commercial satellite imagery vendor Maxar from their WorldView-3 Earth observation satellite under the terms of an agreement with a project partner as part of NASA High-Mountain Asia Grant 80NSSC20K1595. Data licencing terms prohibit sharing of these data in the public domain. We additionally used new Pléiades DEMs to support the creation of the geomorphological segment shapefiles. These data are included in the data collection.
