Method and provenance

Production method

The provider overlaid Overture building footprints and IHME 2026 population estimates on the UNOSAT damage-analysis area.

Provenance

Produced by Microsoft AI for Good Lab and published through HDX; upstream sources stated by the provider are Overture Maps, IHME 2026 population estimates, and UNOSAT damage analysis.

Validation

Unclear

Uncertainty

No separate validation or uncertainty statement is supplied. Results inherit the coverage, classification, and temporal limitations of the UNOSAT impact area, Overture footprints, and IHME population surface.

Limitations

The stated results apply to the provider-identified 37 km² impact area. The 157.1 MiB building GeoPackage was reviewed from authoritative metadata only because full retrieval was unnecessary; the companion population raster was structurally inspected.
