Catalogue assessment and metadata evidenceAssessment recorded
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 Supporting Metadata
- 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
- Supporting
- Scientific validation
- not_performed_by_catalogue_review
- Rights
- NASA NISAR science data documented free/open; Earthdata registration required for protected science routes
- Coverage Interpretation
- Native acquisition and footprint are parent-scene properties, not preview georeferencing
- Recorded access
- Registration Required As Documented
- Source assessment
- Native source identity, relation to event or baseline, information role and available access route meet the inventory scope.
- Limitations
- Urgent-response radar product. Its processing level and radar parameters do not alone establish flood extent or field-validated damage.; NASA documents free Earthdata registration. This review did not sign in or retrieve protected science files; anonymous denial is not a finding that the dataset is unavailable.
