Wildfire Hazard Potential, Version 2020 Continuous (Image Service)

Wildfire hazard potential (WHP) is an index that depicts the relative potential for wildfire that would be difficult for suppression resources to contain, based on wildfire simulation modeling. This dataset produced by the USDA Forest Service, Fire Modeling Institute in 2020 shows WHP at a spatial resolution of 270 meters across the entire conterminous United States, classified into five WHP classes of very low, low, moderate, high, and very high. Areas mapped with higher WHP values represent fuels with a higher probability of experiencing torching, crowning, and other forms of extreme fire behavior under conducive weather conditions, based primarily on 2014 landscape conditions. This WHP dataset is based on outputs of wildfire simulation modeling published in 2020.Starting with the 2020 version, the WHP dataset is integrated with the Wildfire Risk to Communities project. The 2020 dataset is the first version to include Alaska and Hawaii. There is a spatially-refined, 30-m resolution version of the WHP as part of the downloadable Wildfire Risk to Communities data, and related datasets that depict other components of wildfire hazard and risk to homes.This 2020 version supersedes all previous versions of Wildfire Hazard Potential (2018, 2014) or Wildland Fire Potential (2012, 2010, 2007). We generally do not advise direct comparisons between versions because changes can reflect improvements in methodology at all stages of the WHP calculation in addition to actual land cover changes.For more information and to download the raster data, please visit the Wildfire Hazard Potential website.Map author: Greg Dillon, USDA Forest Service, Rocky Mountain Research Station, Fire Modeling InstituteThis record was taken from the USDA Enterprise Data Inventory that feeds into the https://data.gov catalog.

野火危害潜力（WHP）指数，系基于野火模拟模型，描绘了难以被扑灭资源所控制的相对野火潜力的指标。本数据集由美国农业部森林服务局、火灾模拟研究所于2020年制作，以270米的空间分辨率展示了整个美国大陆的WHP，并将其分为五个等级：极低、低、中等、高和极高。WHP值较高的区域代表在适宜的气象条件下，燃料更易发生燃烧、树冠燃烧及其他极端火行特征的较高概率，主要基于2014年的景观条件。此WHP数据集基于2020年发布的野火模拟模型输出。自2020版起，WHP数据集与社区野火风险项目相结合。2020版本是首次包含阿拉斯加和夏威夷的数据集。作为可下载的社区野火风险数据及相关数据集的一部分，WHP还提供了一种空间精细化的30米分辨率版本，这些数据集描绘了其他野火危害和风险因素。2020版本取代了所有之前的野火危害潜力（2018、2014）或野地火潜力（2012、2010、2007）版本。我们通常不建议直接比较各版本，因为变化可能反映了WHP计算全过程中方法论的改进，以及实际土地覆盖的变化。如需更多信息及下载栅格数据，请访问野火危害潜力网站。地图作者：Greg Dillon，美国农业部森林服务局，落基山研究站，火灾模拟研究所。本记录源自为https://data.gov目录提供数据的美国农业部企业数据目录。本记录的数据资源包括以下内容：ISO-19139元数据、ArcGIS Hub数据集、ArcGIS GeoService。欲获取完整信息，请访问https://data.gov。
