FireTools Cloud Results - NPWS West Branch

FireTools Cloud is a web-based GIS processing environment developed by the NSW Bushfire Risk Management Research Hub, a NSW focused research partnership between the NSW Department of Planning, Industry and Environment, the University of Wollongong, Western Sydney University, the University of NSW, the University of Tasmania, the University of Melbourne and the NSW Rural Fire Service. It is designed to replicate and replace the functionality of the FireTools II ArcGIS processing plugin to assist in fire management planning. Users upload a datapack containing the GIS files used to run a standard FireTools II analysis, configure the layers and fields that define the analysis, and submit the analysis for processing. After processing is complete, users can download a results pack containing GIS files with analysis results. Selected results are distributed for use as described below.\r\n\r\nResults are true and correct only for the reserves within the NPWS West Branch. Fire history outside the reserves is incomplete so results should not be relied upon.\r\n\r\nLayers in this data package:\r\nHeritage threshold status: Input vegetation classified into LongUnburnt, WithinThreshold, Vulnerable, TooFrequentlyBurnt, Unknown and NoFireRegime (raster and vector). This layer is used to monitor the status of vegetation across the study area with respect to its biodiversity-related impacts of fire.\r\n\r\nNumber of times burnt: The number of times any given point within the study area has been intersected by a burnt area polygon in the fire history (raster and vector)\r\n\r\nTime Since Last Fire: The number of years since any given point within the study area has been intersected by a burnt area polygon in the fire history (raster and vector)\r\n\r\nTime Since Last Fire SFAZ: The number of years since any given Strategic Fire Advantage Zone (SFAZ) within the study area has been intersected by a burnt area polygon in the fire history. This is then classified into 3 time slices whereby 0-6 years = Recently Treated, 7-10 years = Monitor OFH in the field and >10 years = Priority for Assessment and Treatment. (raster and vector). This layer is used to find candidate burn blocks to assess for addition into a hazard reduction program of works.\r\n\r\nVegcode: A simple display layer showing the input vegetation groups over the study area. This is not a fully attributed vegetation layer – it is designed as a simple visual (raster only).\r\n\r\nVegBase. This is a copy of the input veg used, showing just the VEG code, MIN, MAX. Can be used to analyse what is driving results in a given location.\r\n\r\nData is updated up to 4 times per year.

FireTools Cloud 是由新南威尔士州林火风险管理研究中心（NSW Bushfire Risk Management Research Hub）开发的基于网页的地理信息系统（Geographic Information System，GIS）处理环境。该研究中心为新南威尔士州规划、产业与环境部、伍伦贡大学、西悉尼大学、新南威尔士大学、塔斯马尼亚大学、墨尔本大学以及新南威尔士州农村消防局之间的州内研究合作项目。其设计目标为复刻并替代FireTools II ArcGIS处理插件的功能，以辅助林火管理规划工作。用户需上传包含用于执行标准FireTools II分析的GIS文件的数据包，配置定义分析所需的图层与字段，随后提交分析以启动处理流程。处理完成后，用户可下载包含带有分析结果的GIS文件的结果数据包。部分选定的结果将按照如下方式分发使用。

仅针对国家公园与野生动物服务局西分部（National Parks and Wildlife Service，NPWS West Branch）辖区内的保护区，本分析结果真实准确。保护区外的火灾历史数据并不完整，因此不得依赖本结果开展相关工作。

本数据包包含如下图层：
- 遗产阈值状态（Heritage threshold status）：将输入植被划分为未焚烧时长过长（LongUnburnt）、阈值范围内（WithinThreshold）、易受火灾影响（Vulnerable）、焚烧频率过高（TooFrequentlyBurnt）、状态未知（Unknown）以及无火灾管理机制（NoFireRegime）六类，包含栅格与矢量两种格式。该图层用于监测研究区内植被在火灾相关生物多样性影响方面的现状。
- 焚烧次数（Number of times burnt）：统计研究区内任意点位在火灾历史数据中被焚烧区域多边形覆盖的总次数，包含栅格与矢量两种格式。
- 距上次火灾时长（Time Since Last Fire）：计算研究区内任意点位自最近一次被焚烧区域多边形覆盖以来的时长（以年为单位），包含栅格与矢量两种格式。
- 战略火灾优势区距上次火灾时长（Time Since Last Fire SFAZ）：计算研究区内任意战略火灾优势区（Strategic Fire Advantage Zone，SFAZ）自最近一次被焚烧区域多边形覆盖以来的时长（以年为单位）。随后将该时长划分为三个时间区间：0~6年为「近期已处置区」、7~10年为「需实地监测OFH区」、10年以上为「优先评估与处置区」。该图层包含栅格与矢量两种格式，用于筛选候选火烧区块，以评估其是否可纳入减灾处置计划。
- 植被编码（Vegcode）：一款简易可视化图层，用于展示研究区内的输入植被分组。该图层并非全属性植被图层，仅作为简易可视化工具使用（仅支持栅格格式）。
- VegBase：为输入植被数据的副本，仅显示植被编码（VEG code）、最小值（MIN）与最大值（MAX），可用于分析特定区域内分析结果的驱动因素。

本数据每年更新四次。
