El Salvador Risk Assessment Indicators: District-Level Flood and Access Data

HeiGIT provides risk assessment indicators for El Salvador aggregated at the administrative level 2 (districts) to support flood hazard analysis. The dataset integrates data from WorldPop, OpenStreetMap, and Google Earth Engine to quantify demographics, infrastructure access, and facility counts. It was last updated in March 2026.

Use Cases

• Disaster response planning using access_pop_hospitals_30min to identify areas with poor medical reach
• Vulnerability assessment for children by analyzing children_u5 and pop_u15 alongside flood exposure layers
• Infrastructure gap analysis by comparing education_count and primary_healthcare_count across different ADM2 regions

Strengths

• Aggregated at admin level 2 for localized district-level analysis
• Includes specific travel-time accessibility indicators (30min, 1h, 2h) derived from openrouteservice
• Integrates multiple authoritative sources including WorldPop and OpenStreetMap

Limitations

• Facility counts are dependent on OpenStreetMap completeness, which may have regional variations
• Temporal alignment between WorldPop demographics and OSM facility data may not be perfectly synchronized
