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

HeiGIT provides risk assessment indicators for Namibia at the admin level 2 (district) scale, integrating data from WorldPop, OpenStreetMap, and Google Earth Engine. The dataset includes demographic, infrastructure, and flood exposure metrics updated as of March 2026. It is specifically designed to support structured risk assessments for flood hazards across the country's administrative divisions.

Use Cases

• Analyzing healthcare accessibility by comparing access_pop_hospitals_30min against total female_pop or elderly counts
• Planning disaster response for flood events using NAM_ADM2_flood_exposure and NAM_ADM2_coping capacity scores
• Identifying educational infrastructure gaps by mapping education_count across different ADM2_PCODE regions

Strengths

• Aggregated at admin level 2 for localized district-level analysis
• Includes travel-time accessibility metrics derived from openrouteservice
• Integrates multiple high-quality sources including WorldPop and OpenStreetMap

Limitations

• Potential undercounting of facilities in areas with low OpenStreetMap contributor activity
• Methodology for composite coping capacity scores is not explicitly detailed
