Dianjian-1 imagery — Gyirong County, 27 August 2026 | Publicly Available Data Resources for the 2026 Nepal Glacier-Related Hazard Cascade

Resource details

Summary: Dianjian-1 imagery — Gyirong County, 27 August 2026. The NODA record provides metadata, an image preview and an access-application route. The catalogue entry does not establish unrestricted access to the source imagery.
Review findings: Automated metadata inventory from RUN-20260905-011. Eligibility, provenance and mandatory metadata remain under review. No independent human review or image-body inspection is claimed. Provider claims 6 data files, but no file-level science manifest or download was exposed; these are not included in the enumerated asset count. All 2 asset metadata records were assessed in REV-20260907-ASSETS-001; 2 have flagged follow-up. Asset screening and field evidence are available in the metadata review export. This does not assign resource eligibility or manuscript inclusion.
