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 Data
Assessment date: 28 September 2026
Decision reason: The original Microsoft/HDX description reports intersecting Overture building footprints and IHME population estimates within an interpreted affected area: 4,977 footprints and a population estimate of 10,203.8. It is exposure estimation, not building-damage grading or a count of confirmed affected people. Both native URLs are listed; TIFF access was checked by header only and the GPKG exceeded the bounded download limit.
