Description
HeiGIT provides risk assessment indicators for Hungary at the administrative level 2 (districts) to support flood hazard and resilience analysis. The dataset integrates demographic, infrastructure, and accessibility data derived from WorldPop, OpenStreetMap, and Google Earth Engine as of March 2026. It covers multiple dimensions of risk including coping capacity, vulnerability, and flood exposure across all Hungarian districts.
Use Cases
Evaluating healthcare resilience by mapping access_pop_hospitals_30min against the elderly population count
Identifying high-risk infrastructure by overlaying flood_exposure with education_count and primary_healthcare_count
Planning disaster response for vulnerable groups using children_u5 and female_pop demographic fields
Strengths
Admin level 2 granularity for sub-national risk analysis
Includes travel-time accessibility metrics (30/60/120 mins) via openrouteservice
Standardized ADM2_PCODE for integration with HDX COD-AB boundaries
Limitations
Potential undercounting of facilities like hospitals_count due to reliance on OpenStreetMap crowdsourced data
Temporal staleness may occur if the underlying WorldPop or OSM source data is not frequently synced
