La versión de Earth Engine del conjunto de datos de Fire Information for Resource Management System (FIRMS) contiene el producto de detección de incendios de LANCE en formato rasterizado. LANCE procesa las ubicaciones de incendios activos casi en tiempo real (NRT) con el producto estándar de anomalías térmicas y de incendios MOD14/MYD14 de MODIS. Cada ubicación de incendio activa representa el centroide de un píxel de 1 km que el algoritmo marca como que contiene uno o más incendios dentro del píxel. Los datos se rasterizan de la siguiente manera: para cada punto de incendio activo de FIRMS, se define un cuadro delimitador (BB) de 1 km; se identifican los píxeles en la proyección sinusoidal de MODIS que intersecan el BB de FIRMS; si varios BB de FIRMS intersecan el mismo píxel, se conserva el que tiene mayor confianza; en caso de empate, se conserva el más brillante.
Los datos del conjunto de datos casi en tiempo real no se consideran de calidad científica.

Es un nivel de confianza de detección que tiene como objetivo ayudar a los usuarios a evaluar la calidad de los píxeles de incendios activos individuales. La estimación de confianza varía entre el 0% y el 100% para todos los píxeles de incendio dentro de la máscara de incendio. El campo de confianza debe usarse con precaución, ya que es probable que su significado varíe en diferentes partes del mundo.

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.
