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
- The terrain in both panels is historical SRTM; only the radar tone changes. This is not post-collapse topography.
- Rights status
- Package License Stated
- Rights note
- Source states CC-BY-4.0. Apply it only to the documented asset scope; separate upstream data and imagery terms remain applicable.
- Redistribution
- Metadata and links only; no third-party asset bodies published by this catalogue.
