Diagram: GIS combines location-based layers for decisions. Labels: GIS combines location-based layers for decisions | GIS combines location-based layers for decisions | Hazard layer | Flood extent / slope / drought | Exposure layer | People, homes, roads, hospitals | Resources layer | Shelters, teams, water supply | Decision supported | Which places face danger? Who needs | assistance? Which route is usable? Where | should resources go? | Check data dates, accuracy and field reports; a map is decision support.

1. Assess spatial damage. Compare pre-event records with imagery and field surveys to map damaged buildings, roads, crops and utilities.
2. Prioritise restoration. Locate hospitals, drinking-water systems and isolated settlements so critical services and access are restored in a reasoned sequence.
3. Match needs and resources. Map shelter, livelihoods and assistance coverage to reveal underserved areas; verify needs with affected communities.
4. Plan safer reconstruction. Overlay hazard and land-use constraints to avoid rebuilding critical assets in the same high-risk locations.
5. Monitor progress. Update repair status, housing completion and access to services. A shared map reduces duplication and supports transparent review.
6. Review and protect data. Document uncertainty and survey dates, correct discrepancies and limit access to sensitive personal information.
