Wildfire Risk to Communities Community Wildfire Risk Reduction Zones (10-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.

本数据出版物包含社区森林火灾风险降低区域的栅格数据，这些数据作为森林火灾对社区风险项目的一部分提供。其中包含两种类型的数据：1) 划分美国大陆、阿拉斯加和夏威夷所有居住区社区森林火灾风险降低区域的栅格空间数据；2) 由社区、县、部落地区和州根据森林火灾风险降低项目（WRC）生成的火灾风险和风险概要的表格数据。社区森林火灾风险降低区域（CWiRRZ）产品是一张30米分辨率的栅格，用于界定在降低活动对保护住宅免受大多数类型森林火灾最为有效的区域。这些区域由森林火灾可能性（燃烧概率）与居住区的空间耦合关系确定。存在四个风险降低区域：最小暴露区、间接暴露区、直接暴露区和火灾传播区。然而，CWiRRZ栅格可以进一步细分为十个区域，其中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数据的一些交互式网络应用程序，请访问森林火灾风险降低项目（WRC）网站：https://www.wildfirerisk.org。这些数据被视为WCR 2.0的一部分，还包括：1) Scott等人（2024年）关于所有土地的森林火灾风险数据，以及2) Jaffe等人（2024年）关于仅存在住房单位的土地的森林火灾风险数据。此记录来源于美国农业部企业数据目录，该目录输入至https://data.gov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地理服务。欲获取完整信息，请访问https://data.gov。
