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 · Include Data
- Assessment date
- 28 September 2026
- Decision reason
- Native source identity, relation to event or baseline, information role and available access route meet the inventory scope.
- Information role
- Analysis Input
- Scientific validation
- not_performed_by_catalogue_review
- Recorded access
- Reachable Without Authentication
- Source assessment
- Native source identity, relation to event or baseline, information role and available access route meet the inventory scope.
- Limitations
- The raster records VV backscatter change, not a mapped failure scar. Its dB conversion is inferred by the author and not absolutely calibrated; the 6 dB delineation threshold is arbitrary.
- 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.

- Establish the export’s radiometric encoding before quantitative reuse; source-inferred scaling is not independently calibrated here.
