Pléiades 2019 — source-area baseline DEMs | Publicly Available Data Resources for the 2026 Nepal Glacier-Related Hazard Cascade

Resource details

Summary: Five pre-event elevation surfaces plus a rendered preview, released to support analysis of the 2026 source area.
Review findings: The filledCop 30 variant combines epochs and can introduce artefacts; provider excludes it from elevation-change analysis. The merged 2 m variant includes coarser gap fills. DEM licence CC-BY-NC4.0; source imagery has separate CNES access terms. Automated appraisal; no independent human screening or manuscript inclusion assigned. Asset assessment REV-20260908-ASSETS-002 completed 8 newly added or rediscovered asset records; 1 retain explicit follow-up. Titles, technical fields, source versions and interpretation limits are recorded in the asset-review export. Resource eligibility and manuscript inclusion remain separate.
