Flood-affected area comparison — Gerkhutar, Charter 1209-13 | Publicly Available Data Resources for the 2026 Nepal Glacier-Related Hazard Cascade

Resource details

Summary: Event-specific analytical or comparative map distributed through International Charter activation 1052.
Review findings: Automated screening suggests potential eligibility. Official activation record identifies an event-specific map or pre/post image interpretation with public map links. Content and method detail remain provisional until bounded map/metadata inspection. Do not use the product creation timestamp as an image acquisition time. vapCopyright is inconsistent across records and is not accepted automatically as a producer name. Satellite-image copyrights do not establish reuse permission for derived products. Independent human screening and manuscript inclusion remain pending. All 4 asset metadata records were assessed in REV-20260907-ASSETS-001; 0 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.
