Earth Engine 버전의 Fire Information for Resource Management System (FIRMS) 데이터 세트에는 래스터화된 형태의 LANCE 화재 감지 제품이 포함되어 있습니다. 거의 실시간 (NRT) 활성 화재 위치는 표준 MODIS MOD14/MYD14 화재 및 열 이상 제품을 사용하여 LANCE에서 처리합니다. 각 활성 화재 위치는 알고리즘에서 픽셀 내에 하나 이상의 화재가 포함된 것으로 표시한 1km 픽셀의 중심을 나타냅니다. 데이터는 다음과 같이 래스터화됩니다. 각 FIRMS 활성 화재 지점에 대해 1km 경계 상자 (BB)가 정의됩니다. FIRMS BB와 교차하는 MODIS 사인 곡선 투영의 픽셀이 식별됩니다. 여러 FIRMS BB가 동일한 픽셀과 교차하는 경우 신뢰도가 높은 픽셀이 유지됩니다. 동점인 경우 더 밝은 픽셀이 유지됩니다.

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.
