Where this data comes from

Perimeters come from EFFIS (Copernicus, CC BY 4.0) and municipal boundaries from geoBoundaries/geoBoundaries, DG Territory (CC0 1.0 Universal (CC0 1.0) Public Domain Dedication). The area per municipality is computed by WorldFires by crossing both. The forecast is from Open-Meteo (CC BY 4.0).
