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: 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: Seven historical difference rasters share a 30 m grid in EPSG:32645. File names label 1964–1974, 1964–2019, 1974–2004, 2004–2009, 2009–2015, 2015–2017 and 2017–2019. These are baseline changes, not the 2026 event.
