Applications
- 9.6.1 Slum Mapping & Growth Tracking — Continuously delineating informal settlement boundaries and detecting lateral growth or densification using multispectral and SAR satellite imagery at sub-5m resolution.
- 9.6.2 Informal Economy Indicators — Using multispectral and very-high-resolution satellite imagery to proxy informal economic activity — market density, rooftop solar adoption, construction churn and night-light intensity — in settlements outside the formal statistical record.
- 9.6.3 Service Gap Identification — Using multispectral and SAR satellite imagery to locate informal settlements without piped water, grid electricity, paved roads or sanitation infrastructure, at city-wide scale.
- 9.6.4 In-Situ Upgrading Verification — Using repeat-pass satellite imagery and change detection to independently verify that physical upgrading works in informal settlements are progressing as contracted and funded.
- 9.6.5 Disaster Vulnerability Mapping — Using multi-modal satellite imagery and elevation data to identify which informal settlements face the greatest exposure to floods, landslides, and seismic hazard.
