Guinea Risk Assessment Indicators: 7 District-Level Data Layers

HeiGIT provides seven layers of risk assessment indicators for Guinea at the administrative level 2 (districts) to support flood hazard analysis. The data integrates demographic, infrastructure, and accessibility metrics derived from WorldPop and OpenStreetMap as of March 2026. It includes specific travel-time accessibility figures and population breakdowns for vulnerable groups.

Use Cases

• Flood risk modeling using GIN_ADM2_flood_exposure to identify high-risk districts
• Healthcare accessibility analysis using access_pop_hospitals_30min to measure service gaps
• Vulnerable population mapping using children_u5 and elderly columns for humanitarian aid targeting

Strengths

• Aggregated at administrative level 2 (districts)
• Includes 7 distinct thematic layers for risk assessment
• Provides travel-time metrics (30, 60, 120 minutes) for service access

Limitations

• Facility counts (education_count, hospitals_count) are subject to OpenStreetMap crowdsourcing bias and incompleteness
• Missing column definitions for the rural population layer
