Chile Risk Assessment Indicators for Flood Hazards at Admin Level 2

Seven indicator layers provide demographic, environmental, infrastructure, accessibility, and hazard-related data for Chile's administrative level 2 districts. The dataset is derived from HeiGIT's GAIA Pipeline, integrating open data from WorldPop, OpenStreetMap, and Google Earth Engine. It was last updated on 2026-04-13.

Use Cases

• Assess population exposure to flood hazards based on flood exposure indicators.
• Evaluate district coping capacity by combining access to services and facility count data.
• Analyze demographic vulnerability for disaster planning using age and gender composition data.
• Model accessibility to critical services like hospitals and schools using travel time and distance metrics.

Strengths

• Includes seven distinct indicator layers covering demographics, facilities, access, vulnerability, and flood exposure.
• Aggregated at a standardized administrative level (ADM2) using HDX COD-AB boundaries.
• Integrates multiple authoritative open data sources including WorldPop, OpenStreetMap, and Google Earth Engine.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent for the rural_population layer; field semantics must be inferred after download.
