### Q6A. Describe the role of GIS in training and conducting drills considering any one type of natural disaster [10 marks]

#### Answer

Consider a river-flood evacuation drill. GIS helps convert a general plan into a realistic exercise for actual places.

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.

A drill uses a map of both the hazard and the people/resources affected.

1. **Construct a scenario.** Show likely flood extent and depth and identify settlements that would need evacuation.
2. **Map people and routes.** Locate schools, hospitals, people needing assistance, roads and bridges; identify bottlenecks and alternate routes.
3. **Select safe destinations.** Check shelter location, accessibility and capacity and avoid routes crossing the forecast flood zone.
4. **Allocate teams and resources.** Assign wardens, transport, first-aid points and communication responsibilities to mapped areas.
5. **Rehearse changing conditions.** During the exercise mark a simulated bridge closure and require teams to select a safe alternative using the shared map.
6. **Evaluate performance.** Record movement times, coverage and unresolved assistance needs; update maps and plans. A shorter evacuation time alone is not success if people were left behind.

#### Real programme and application · Satellite flood mapping

NRSC’s disaster-management support uses space-based information to assist decisions. A flood map can be combined with settlement and road layers to identify affected access routes. The imagery shows conditions at a particular observation time; responders must check its age and ground accuracy.
