Where this data comes from

Perimeters come from GWIS (Copernicus, CC BY 4.0), rebuilt from heat detections, and municipal boundaries from geoBoundaries/geoBoundaries, Wikimedia Commons (Creative Commons Attribution 2.5 Generic). The area per municipality is computed by WorldFires by crossing both. The forecast is from Open-Meteo (CC BY 4.0).
