Tennessee Wildfire Hazard Potential (Hexagon Grid)

Tennessee Wildfire Hazard Potential (Hexagon Grid) Overview This feature layer represents Wildfire Hazard Potential (WHP) across Tennessee using a statewide hexagonal grid system. The polygons in this dataset are 50-square-kilometer hexagon grids that provide a consistent spatial framework for identifying and analyzing areas where wildfire may be more difficult to manage. The data is derived from the USFS National Wildfire Hazard Potential dataset, produced by the USDA Forest Service, Rocky Mountain Research Station, with supporting wildfire hazard modeling from Pyrologix LLC. Wildfire Hazard Potential is an index that quantifies the relative potential for wildfire that may be difficult to manage and is commonly used to help prioritize where fuel treatments, mitigation efforts, and fire prevention strategies may be needed. This dataset is intended for use in wildfire risk assessment, forestry planning, fuel treatment prioritization, fire prevention planning, emergency management coordination, research, and public information purposes. It serves as a GIS reference layer for evaluating relative wildfire hazard patterns across Tennessee at a regional planning scale. Feature Layer WHP Hexagon Grids: This polygon layer represents 50-square-kilometer hexagon grid cells covering Tennessee. Each hexagon is associated with a Wildfire Hazard Potential classification and grid identification code. The layer provides a generalized spatial framework for analyzing relative wildfire hazard potential and supporting statewide wildfire planning, mitigation, and management activities. Data Attributes ClassCode: The Wildfire Hazard Potential classification assigned to the hexagon. Data Maintenance This layer is maintained by the TDF Forest Data and Analysis Unit. It is updated periodically as needed to reflect updated source data from the USFS National Wildfire Hazard Potential dataset, revised wildfire hazard modeling methods, improved source datasets, boundary refinements, or other administrative changes.田纳西州野火风险潜力（六边形网格）概述 本要素图层采用全州六边形网格系统，展示田纳西州全域的野火风险潜力（Wildfire Hazard Potential, WHP）。本数据集的多边形单元为50平方千米的六边形网格，可为识别与分析野火管控难度较高的区域提供统一的空间分析框架。本数据源自美国农业部林务局（United States Department of Agriculture Forest Service, USDA Forest Service）落基山研究站编制的USFS国家野火风险潜力数据集，并辅以Pyrologix有限责任公司提供的野火风险建模支持。 野火风险潜力是一项用于量化野火管控难度较高事件相对发生可能性的指数，通常用于优先划定需开展燃料处理、减灾行动及防火策略的区域。本数据集可应用于野火风险评估、林业规划、燃料处理优先级排序、防火规划、应急管理协调、学术研究及公共信息发布等场景，可作为区域规划尺度下评估田纳西州全域野火风险潜力空间分布的地理信息系统（Geographic Information System, GIS）参考图层。 要素图层 WHP 六边形网格： 本多边形图层涵盖覆盖田纳西州全域的50平方千米六边形网格单元，每个六边形均关联野火风险潜力分类代码与网格标识码。本图层提供了通用空间框架，用于分析相对野火风险潜力，并支撑全州野火规划、减灾与管理相关工作。 数据属性： ClassCode：分配至该六边形的野火风险潜力分类代码。 数据维护： 本图层由TDF森林数据与分析单元负责维护，将根据USFS国家野火风险潜力数据集的更新源数据、修订的野火风险建模方法、优化后的源数据集、边界调整或其他行政变更等情况定期按需更新。
