Sao Tome and Principe Risk Assessment: ADM2 Infrastructure and Flood Data

Giving access to risk assessment indicators for Sao Tome and Principe aggregated at the administrative level 2 (district), focusing on flood hazards and infrastructure accessibility. Developed by the Heidelberg Institute for Geoinformation Technology (HeiGIT) via the GAIA Pipeline, it integrates data from WorldPop, OpenStreetMap, and Google Earth Engine as of March 2026.

Use Cases

• Evaluating disaster resilience by cross-referencing STP_ADM2_flood_exposure with district-level coping capacity
• Identifying healthcare gaps by analyzing access_pop_primary_healthcare_30min relative to the female_pop and elderly columns
• Planning educational infrastructure by comparing education_count against the pop_u15 demographic

Strengths

• Aggregated at the granular ADM2 level for localized district analysis
• Includes multi-modal travel-time metrics (30, 60, and 120 minutes) derived from openrouteservice
• Integrates high-resolution demographic data from WorldPop

Limitations

• Facility counts such as education_count and hospitals_count are dependent on OpenStreetMap completeness, which may vary by district
• The coping capacity indicator is a composite index which may mask underlying variance in the raw accessibility data
