La version Earth Engine de l'ensemble de données FIRMS (Fire Information for Resource Management System) contient le produit de détection d'incendie LANCE sous forme rasterisée. Les emplacements des incendies actifs en temps quasi réel sont traités par LANCE à l'aide du produit standard MODIS MOD14/MYD14 Fire and Thermal Anomalies. Chaque emplacement d'incendie actif représente le centroïde d'un pixel de 1 km qui est signalé par l'algorithme comme contenant un ou plusieurs incendies dans le pixel. Les données sont rasterisées comme suit : pour chaque point d'incendie actif FIRMS, une zone de délimitation (ZD) de 1 km est définie. Les pixels de la projection sinusoïdale MODIS qui croisent la ZD FIRMS sont identifiés. Si plusieurs ZD FIRMS croisent le même pixel, celui avec la plus grande confiance est conservé. En cas d'égalité, le plus lumineux est conservé.
Les données de l'ensemble de données quasi en temps réel ne sont pas considérées comme étant de qualité scientifique.

Il s'agit d'une fiabilité de la détection qui permet aux utilisateurs d'évaluer la qualité des pixels de feu actif individuels. L'estimation de la fiabilité varie entre 0 % et 100 % pour tous les pixels d'incendie dans le masque d'incendie. Le champ de confiance doit être utilisé avec prudence, car sa signification varie probablement selon les régions du monde.

The near real-time (NRT) active fire locations are\nprocessed by LANCE using the standard MODIS MOD14/MYD14 Fire and Thermal\nAnomalies product. Each active fire location represents the centroid of a\n1km pixel that is flagged by the algorithm as containing one or more fires\nwithin the pixel. The data are rasterized as follows: for each FIRMS active\nfire point, a 1km bounding box (BB) is defined; pixels in the MODIS\nsinusoidal projection that intersect the FIRMS BB are identified; if\nmultiple FIRMS BBs intersect the same pixel, the one with higher confidence\nis retained; in case of a tie, the brighter one is retained.\n\nThe data in the near-real-time dataset are not considered to be of science\nquality.\n\nAdditional information can be found [here](https://firms.modaps.eosdis.nasa.gov/).\n\nNOTE: VIIRS FIRMS datasets from NOAA20 and SUOMI are also available:\n\n- [NASA/LANCE/NOAA20_VIIRS/C2](/earth-engine/datasets/catalog/NASA_LANCE_NOAA20_VIIRS_C2)\n- [NASA/LANCE/SNPP_VIIRS/C2](/earth-engine/datasets/catalog/NASA_LANCE_SNPP_VIIRS_C2)\n\nBands\n\n\n**Pixel Size**\n\n1000 meters\n\n**Bands**\n\n| Name | Units | Min | Max | Pixel Size | Description |\n|---------------|-------|-------|----------|------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| `T21` | K | 300\\* | 509.29\\* | meters | The brightness temperature of a fire pixel using MODIS channels 21/22. |\n| `confidence` | % | 0 | 100 | meters | A detection confidence intended to help users gauge the quality of individual active fire pixels.
