FireTools Cloud Results - NPWS Southern Ranges 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 Southern Ranges 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是一个基于网络的地理信息系统（GIS）处理环境，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——该中心是专注于新南威尔士州（NSW）的研究合作机构，合作方包括新南威尔士州规划、工业与环境部、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乡村消防局。其设计旨在复制并替代FireTools II ArcGIS处理插件的功能，以辅助林火管理规划。用户上传包含GIS文件的数据包（datapack），这些文件用于运行标准的FireTools II分析；随后配置定义分析的图层与字段，并提交分析任务进行处理。处理完成后，用户可下载包含分析结果GIS文件的结果包。部分选定结果的分发用途如下所述。

结果仅对新南威尔士州国家公园与野生动物管理局（NPWS）南部区域分局管辖范围内的保护区有效。保护区外的林火历史数据不完整，因此不应依赖这些区域的结果。

本数据包中的图层包括：
Heritage threshold status：输入植被被划分为长期未燃烧（LongUnburnt）、阈值范围内（WithinThreshold）、脆弱（Vulnerable）、燃烧过于频繁（TooFrequentlyBurnt）、未知（Unknown）及无火生态型（NoFireRegime）六个类别（栅格与矢量格式）。该图层用于监测研究区域内植被的状态，评估林火对生物多样性的影响。

Number of times burnt：研究区域内任意点在林火历史中被燃烧区域多边形覆盖的次数（栅格与矢量格式）。

Time Since Last Fire：研究区域内任意点自上次被燃烧区域多边形覆盖以来的年数（栅格与矢量格式）。

Time Since Last Fire SFAZ：研究区域内任意战略防火优势区（SFAZ）自上次被燃烧区域多边形覆盖以来的年数。随后将其划分为3个时间片：0-6年=近期处理、7-10年=实地监测林火历史（OFH）、>10年=评估与处理优先级（栅格与矢量格式）。该图层用于筛选候选燃烧区块，以评估是否纳入减灾工程计划。

Vegcode：显示研究区域内输入植被组的简易展示图层。它并非完全属性化的植被图层，仅用作简易可视化（仅栅格格式）。

VegBase：这是所用输入植被数据的副本，仅显示VEG代码、最小值（MIN）、最大值（MAX）。可用于分析特定位置结果的驱动因素。

数据每年更新至多4次。
