Wildfire Risk to Communities Community Wildfire Risk Reduction Zones (4-Category) (Image Service)

This data publication includes Community Wildfire Risk Reduction Zone rasters, products delivered as part of the Wildfire Risk to Communities project. There are two types of data included: 1) raster spatial data that delineate Community Wildfire Risk Reduction Zones for all populated areas in the continental United States (CONUS), Alaska, and Hawaii; and 2) tabular summaries by communities, counties, tribal areas, and states of wildfire hazard and risk produced as part of the Wildfire Risk to Communities (WRC) project. The Community Wildfire Risk Reduction Zones (CWiRRZ) product is a 30-m raster delineating areas where mitigation activities will be most effective at protecting homes from most types of wildfire. The zones are determined by the spatial coincidence of wildfire likelihood (Burn Probability), and populated areas. There are four Risk Reduction Zones: Minimal Exposure Zone, Indirect Exposure Zone, Direct Exposure Zone, and Wildfire Transmission Zone. However, the CWiRRZ raster can be further deconstructed into ten zones, wherein the Wildfire Transmission Zone is separated into the following surface fuel types: Tree, Shrub, Grass, Agriculture, Non-Vegetated, Water, and Outlying Wildlands (area beyond 2400-m from buildings). See the Wildfire Risk to Communities (WRC) website at https://www.wildfirerisk.org for complete project information and an interactive web application for exploring some of the data published here. These data are considered part of WCR 2.0 which also includes: 1) Scott et al. (2024) containing data regarding wildfire risk across all lands, and 2) Jaffe et al. (2024) containing wildfire risk across lands where only housing units current exist.This record was taken from the USDA Enterprise Data Inventory that feeds into the https://data.gov catalog.

本数据发布包含社区森林火灾风险降低区域的栅格数据，这些数据作为社区森林火灾风险项目的一部分提供。数据包含两种类型：1) 栅格空间数据，用于划定美国大陆、阿拉斯加和夏威夷所有人口密集地区的社区森林火灾风险降低区域；2) 作为社区森林火灾风险（WRC）项目一部分，按社区、县、部落地区和州编制的森林火灾危害和风险表格概要。社区森林火灾风险降低区域（CWiRRZ）产品是一个30米分辨率的栅格，用于标识在何处进行缓解活动将最有效地保护住宅免受大多数类型森林火灾的侵害。这些区域通过森林火灾发生可能性（燃烧概率）与人口密集区域的时空巧合来确定。存在四个风险降低区域：最小暴露区、间接暴露区、直接暴露区和森林火灾传播区。然而，CWiRRZ栅格可以被进一步分解为十个区域，其中森林火灾传播区被细分为以下地表燃料类型：树木、灌木、草地、农业、非植被、水域和外围荒野（建筑物2400米以外的区域）。有关完整的项目信息和探索此处发布的一些数据的交互式网络应用程序，请访问森林火灾风险社区（WRC）网站：https://www.wildfirerisk.org。这些数据被视为WCR 2.0的一部分，它还包括：1) Scott等（2024）涉及所有土地的森林火灾风险数据；2) Jaffe等（2024）涉及仅存在住房单位的土地的森林火灾风险数据。本记录来源于为https://data.gov目录提供数据的美国农业部企业数据目录。本记录的数据包括以下资源：ISO-19139元数据、ArcGIS Hub数据集、ArcGIS地理服务。如需完整信息，请访问https://data.gov。
