Where this data comes from

Perimeters come from GWIS (Copernicus, CC BY 4.0), rebuilt from heat detections, and municipal boundaries from geoBoundaries/La Biblioteca del Congreso Nacional de Chile (BCN), OCHA ROLAC (Creative Commons Attribution 3.0 Intergovernmental Organisations (CC BY 3.0 IGO)). The area per municipality is computed by WorldFires by crossing both. The forecast is from Open-Meteo (CC BY 4.0).
