Angola Risk Assessment Indicators: District-Level Flood and Infrastructure Data

HeiGIT released this dataset in 2026 providing risk assessment indicators for Angola aggregated at the administrative level 2. It integrates demographic, infrastructure, and flood exposure data from WorldPop, OpenStreetMap, and Google Earth Engine to support disaster resilience analysis.

Use Cases

• Analyzing healthcare accessibility by comparing access_pop_hospitals_30min across different districts
• Identifying vulnerable populations for flood relief using children_u5 and elderly demographic counts
• Evaluating district-level infrastructure density using education_count and primary_healthcare_count

Strengths

• Aggregated at admin level 2 for localized district analysis
• Includes multi-modal accessibility metrics derived from openrouteservice
• Integrates data from high-quality sources like WorldPop and OpenStreetMap

Limitations

• Dependent on OpenStreetMap completeness, which may vary in rural Angolan districts
• Potential temporal staleness of underlying demographic data from WorldPop
