Maldives Risk Assessment: Flood Exposure and Infrastructure at Admin Level 2

Maldives Risk Assessment Indicators provide demographic, infrastructure, and flood exposure data aggregated at the administrative level 2. Produced by the Heidelberg Institute for Geoinformation Technology (HeiGIT) in 2026, the dataset integrates WorldPop and OpenStreetMap data to support disaster resilience analysis.

Use Cases

• Calculating the percentage of vulnerable residents using the elderly and children_u5 columns
• Planning emergency response routes based on access_pop_primary_healthcare_30min travel times
• Assessing district-level resilience by comparing education_count against flood_exposure metrics

Strengths

• Integrates multi-source data from WorldPop, OSM, and Google Earth Engine
• Provides specific travel-time accessibility metrics for hospitals and schools
• Uses standardized ADM2_PCODE for integration with HDX COD-AB boundaries

Limitations

• Facility counts are subject to OpenStreetMap contributor activity and may be incomplete in remote atolls
• Risk indicators are modeled aggregates rather than direct census observations
