Comores Risk Assessment Indicators: Admin Level 2 Flood and Demographic Data

Comores risk assessment indicators aggregated at administrative level 2, produced by the Heidelberg Institute for Geoinformation Technology (HeiGIT) and updated in March 2026. The data integrates demographics from WorldPop, infrastructure from OpenStreetMap, and accessibility metrics from openrouteservice to support flood hazard and resilience analysis.

Use Cases

• Assessing flood risk vulnerability by cross-referencing elderly population counts with COM_ADM2_flood_exposure layers
• Planning emergency response logistics based on access_pop_primary_healthcare_30min travel time metrics
• Identifying infrastructure development needs using education_count and hospitals_count per district

Strengths

• Aggregated at admin level 2 for localized district-level analysis
• Integrates multi-source data from WorldPop, OpenStreetMap, and Google Earth Engine
• Includes specific travel-time accessibility metrics (30min, 1h, 2h) for healthcare facilities

Limitations

• Facility counts (education_count, hospitals_count) are dependent on the completeness of OpenStreetMap contributors
• Demographic data relies on WorldPop spatial modeling rather than a direct contemporary census
