Catalogue assessment and metadata evidence

Follow-up needed

Completed catalogue decisions are recorded separately from technical inspection and scientific validation. Access and metadata evidence retain their original dates and scope.

Completed catalogue assessment

Eligibility decision: Include · Retain Ancillary Preview
Assessment date: 28 September 2026
Decision reason: Original metadata identifies an associated preview. Retain the link without assigning raster measurement properties or independent observation status; no image inspection.
Information role: Preview Not Independent Observation
Scientific validation: not_performed_by_catalogue_review
Recorded access: Reachable Without Authentication
Source assessment: Original metadata identifies an associated preview. Retain the link without assigning raster measurement properties or independent observation status; no image inspection.
Limitations: Historical boulders and palaeoflood estimates provide context. They are not all deposits of the 2026 event.
Rights status: Not Stated
Rights note: StoryMap licenceInfo is empty. Individual figure credits identify upstream contributors; they do not establish a blanket licence for the annotated figure or underlying scientific data.
Redistribution: Metadata and links only; no third-party asset bodies published by this catalogue.
