Description
Humanitarian OpenStreetMap Team (HOT) provides building damage areas for the M7.5 earthquake that struck Venezuela on 24 June 2026. The dataset is generated by AI detection on pre- and post-event very-high-resolution optical imagery, aggregated to an H3 grid, and validated by MapSwipe volunteers. Coverage includes Caraballeda, La Guaira, Caracas, Catia La Mar, Naiguata, and Moron, with El Junquito in process of validation as of July 2026.
Use Cases
Prioritize emergency response efforts based on validated damage areas.
Train or evaluate AI damage detection models using crowdsourced validation labels.
Analyze the spatial distribution of earthquake damage in specific Venezuelan municipalities.
Study the agreement between volunteer validators using the provided vote breakdowns per area.
Strengths
Validation incorporates multiple volunteer reviews per area via the MapSwipe platform.
Provides full vote breakdowns for each hex area, allowing for re-assessment with custom confidence thresholds.
Uses very-high-resolution optical imagery from Vantor Inc. 2026 via OpenAerialMap.
Combines AI detection from HOTOSM fAIr and Microsoft AI for Good Lab with human validation.
Limitations
Validation is based on visual inspection of aerial imagery only and is not ground-truthed.
Coverage may be incomplete due to factors like image resolution and subjective judgments of the crowd.
Column-level documentation is absent; field semantics must be inferred after download.
