Wildfire Hazard Potential, Version 2023 Continuous (Image Service)

This dataset is the 2023 version of wildfire hazard potential (WHP) for the United States. The files included in this data publication represent an update to any previous versions of WHP or wildland fire potential (WFP) published by the USDA Forest Service. WHP is an index that quantifies the relative potential for high-intensity wildfire that may be difficult to manage, used as a measure to help prioritize where fuel treatments may be needed. This 2023 version of WHP was created from updated national wildfire hazard datasets of annual burn probability and fire intensity generated by the USDA Forest Service, Rocky Mountain Research Station with the large fire simulation system (FSim). Vegetation and wildland fuels data from LANDFIRE 2020 (version 2.2.0) were the primary inputs to the updated FSim modeling work and therefore form the foundation for this version of the WHP. As such, the data presented here reflect landscape conditions as of the end of 2020. LANDFIRE 2020 vegetation and fuels data were also used directly in the WHP mapping process, along with updated point locations of fire occurrence ca. 1992-2020. With these datasets as inputs, we produced an index of WHP for all of the conterminous United States at 270-meter resolution. We present the final WHP map in two forms: 1) continuous integer values, and 2) five WHP classes of very low, low, moderate, high, and very high. On its own, WHP is not an explicit map of wildfire threat or risk, but when paired with spatial data depicting highly valued resources and assets such as structures or powerlines, it can approximate relative wildfire risk to those specific resources and assets. WHP is also not a forecast or wildfire outlook for any particular season, as it does not include any information on current or forecasted weather or fuel moisture conditions. It is instead intended for long-term strategic fuels management.This record was taken from the USDA Enterprise Data Inventory that feeds into the https://data.gov catalog.

本数据集为2023年版美国森林火灾危险潜力（WHP）数据集。该数据发布中所包含的文件是对美国农业部森林管理局先前发布的任何WHP或野地火灾潜力（WFP）版本的更新。森林火灾危险潜力指数（WHP）是一种量化高强度森林火灾相对潜力的指标，该火灾可能难以管理，并被用作帮助确定燃料处理优先地区的参考。2023年版WHP是由美国农业部森林管理局洛基山研究站利用大型火灾模拟系统（FSim）生成的一年燃烧概率和火灾强度更新国家森林火灾危险数据集所创建。LANDFIRE 2020（版本2.2.0）中的植被和野地燃料数据是该版本WHP更新建模工作的主要输入，因此构成了该版本WHP的基础。因此，所提供的数据反映了截至2020年底的景观条件。LANDFIRE 2020植被和燃料数据也直接用于WHP制图过程，以及更新了约1992-2020年火灾发生的点位置。利用这些数据集作为输入，我们生成了270米分辨率的美国大陆所有地区的WHP指数。我们以两种形式呈现最终的WHP地图：1）连续整数值，2）五个WHP等级，包括极低、低、中等、高和极高。WHP本身并非森林火灾威胁或风险的明确地图，但当与表示高价值资源如建筑或输电线路的空间数据进行配对时，它可以近似特定资源或资产相对的森林火灾风险。WHP也不是针对任何特定季节的预测或森林火灾展望，因为它不包含关于当前或预测天气或燃料水分条件的信息。相反，它旨在用于长期战略燃料管理。此记录摘自为https://data.gov目录提供数据的美国农业部企业数据目录。此记录的数据包括以下资源：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。
