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 · Included Qualitative Documentation
Assessment date: 28 September 2026
Decision reason: GeoSutra original field page identifies 16 full aerial frames at three surveyed settlements on 27 August and permits reuse with credit. Site coordinates are not frame georeferencing; no orthomosaic, DSM, calibration or complete corridor coverage is established. Thumbnails duplicate full frames. This file has only a preview/illustration role; no independent data-product count.
Information role: Ungeoreferenced Aerial Frame
Scientific validation: not_performed_by_catalogue_review
Access assessment: Reachable Without Authentication
Rights assessment: Provider Statement Not Standard Licence
