Catalogue assessment and metadata evidence

Assessment 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 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: Water Or Flood Classification
Scientific validation: not_performed_by_catalogue_review
Rights: Original STAC collection licence=proprietary; public download access verified separately; no unrestricted redistribution claim
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: Automated water/flood classification or ancillary mask. Item footprint intersection does not verify valid event pixels or local detection performance.
Rights assessment: Original STAC collection licence=proprietary; public download access verified separately; no unrestricted redistribution claim
Assessment evidence: Source 1: stac.eodc.eu
