NSW Interim Native Vegetation Extent (2008-v2).

Various vegetation Extent and Nativeness products, that include: the delineation by woody and non-woody; and maps of the uncertainty associated with assignment of extent and nativeness. The primary product is a NSW Native Vegetation Extent layer prepared for the National Land and Water Resources Audit 2008. This represents native vegetation extent at 2006. A number of other useful intermediate products are also available. Full report is available from http://maps.environment.nsw.gov.au\t\t\t;\r\n;\r\nVEGETATION EXTENT was derived from interim Foliage Projected Cover (FPC) data (FPC 00,02,04,06) prepared by the DECC's Woody Vegetation Change Detection Program in early 2008. FPC is generated from Statewide Landcover And Trees Study (SLATS) methodology, developed in Queensland by Qld Dept of Natural Resources and recently applied in NSW. The SLATS program applies a series of algorithms on Landsat TM data to produce FPC values ranging from 0-100 percent. A threshold (or thresholds) are applied to the FPC data to separate woody from non-woody vegetation. NATIVENESS was derived from interim NSW Land-use Mapping data (Emery et. al), and then used to ascertain whether vegetation may be native or non-native.;\r\n;\r\nCAVEAT:Vegetation extent and nativeness layers generated for this project are interim in nature and are subject to ongoing refinement. While these products represent the best available estimate of vegetation extent and nativeness at this time they will be improved overtime and hence are not suitable for accurate reporting of vegetation change

本数据集涵盖多种植被覆盖范围（Vegetation Extent）与原生性（Nativeness）产品，包括木本与非木本植被的区划结果，以及与覆盖范围和原生性赋值相关的不确定性地图。核心产品为2008年全国土地与水资源审计（National Land and Water Resources Audit）编制的新南威尔士州（New South Wales, NSW）原生植被覆盖范围图层，该图层呈现了2006年的原生植被覆盖状况。此外还提供多项实用的中间产品，完整报告可从http://maps.environment.nsw.gov.au获取。

植被覆盖范围数据源自新南威尔士州环境与气候变更部（Department of Environment and Climate Change, DECC）2008年初通过木本植被变化检测项目生成的临时叶面投影盖度（Foliage Projected Cover, FPC）数据集（涵盖FPC 00、02、04、06四个版本）。FPC的生成基于全州土地覆盖与树木研究（Statewide Landcover And Trees Study, SLATS）方法体系，该方法由昆士兰州自然资源部（Qld Dept of Natural Resources）在昆士兰州开发，近期被应用于新南威尔士州。SLATS项目通过对陆地卫星TM（Landsat TM）遥感数据应用一系列算法，生成取值范围为0至100%的FPC数值。通过对FPC数据设置一个或多个阈值，可区分木本与非木本植被。原生性数据则源自临时新南威尔士州土地利用制图数据集（Emery等人），用于判定植被的原生与非原生属性。

注意事项：本项目生成的植被覆盖范围与原生性图层均为临时成果，仍需持续优化完善。尽管上述产品为当前阶段可获取的最优植被覆盖范围与原生性估算结果，但它们将随时间推移不断改进，因此不适用于植被变化的精准报告。
