Wildfire Risk to Communities Flame Length Exceedance Probability - 8 foot (Image Service)

Metadata Updated: June 21, 2023

This dataset is the Flame Length Exceedance Probability - 8 foot (FLEP8) raster for the United States. It is part of the Wildfire Risk to Communities: Spatial datasets of landscape-wide wildfire risk components for the United States. The values of FLEP8 represent the probability of having flame lengths greater than 8 feet if a fire occurs. FLEP8 indicates the potential for high wildfire intensity. Because 8 feet is near the limit of mechanical fire control, FLEP8 represents the likelihood that fire intensity will be beyond the ability of heavy machinery, such as bulldozers, to control. Vegetation and wildland fuels data from LANDFIRE 2014 (version 1.4.0) form the foundation for the Wildfire Risk to Communities data. As such, the data presented here reflect landscape conditions as of the end of 2014. National wildfire hazard datasets of annual burn probability and fire intensity were generated from the LANDFIRE 2014 data by the USDA Forest Service, Rocky Mountain Research Station (Short et al. 2020) using the large fire simulation system (FSim). These national datasets produced with FSim have a relatively coarse cell size of 270 meters (m). To bring these datasets down to a finer resolution more useful for assessing hazard and risk to communities, we upsampled them to the native 30 m resolution of the LANDFIRE fuel and vegetation data. In this upsampling process, we also spread values of modeled burn probability and intensity into developed areas represented in LANDFIRE fuels data as non-burnable.�Additional methodology documentation is provided with the data publication download.�Metadata and Downloads.Note:�Pixel values in this image service have been altered from the original raster dataset due to data requirements in web services. The service is intended primarily for data visualization. Relative values and spatial patterns have been largely preserved in the service, but users are encouraged to download the source data for quantitative analysis.Short, Karen C.; Finney, Mark A.; Vogler, Kevin C.; Scott, Joe H.; Gilbertson-Day, Julie W.; Grenfell, Isaac C. 2020.
