SLATS LANDSAT Woody Vegetation Change - NSW 1988 - 2010

This dataset was derived from the primary "SLATS Landsat woody change data (25m) for 1988 - 2010" raster (grid) layers used to generate the annualised woody vegetation change rates for the 2010 NSW Annual Report of Native Vegetation.(http://www.environment.nsw.gov.au/vegetation/reports.htm);\r\n;\r\nThis data describes the areas and type of woody vegetation change (loss) based on the analysis of multi-date Landsat imagery covering NSW. This data is based on a biennial LANDSAT coverage between 1988-2006 and annual coverage 2006-2010. LANDSAT Imagery 1988-2008 was processed by Geosciences Australia at 25m resolution. 2008 onwards is based on USGS processed LANDSAT at 30m resolution.;\r\n;\r\nNote, this vector data may generate slightly different aerial statistics to those generated from the source raster data. This is due to variation caused by the data transformation and vector cleaning processes applied in generating the vector data.\r\n\r\nRemotely sensed imagery is routinely collected by DPE and used to map vegetation clearing. This data is spatially explicit and can be used with other datasets to identify activity on individual lots. Please read the privacy collection notice for more information.

本数据集源自用于生成2010年新南威尔士州本土植被年度报告中年度化木本植被变化率的核心"1988-2010年SLATS陆地卫星（Landsat）木本变化数据（25米分辨率）"栅格（raster）图层。（数据来源链接：http://www.environment.nsw.gov.au/vegetation/reports.htm）

本数据集基于覆盖新南威尔士州的多期陆地卫星（Landsat）影像分析，描述了木本植被变化（减少）的范围与类型。1988-2006年采用每两年一次的陆地卫星覆盖数据，2006-2010年则采用年度覆盖数据。1988-2008年的陆地卫星影像由澳大利亚地球科学局（Geosciences Australia）以25米分辨率处理生成；2008年之后的数据则基于美国地质调查局（United States Geological Survey，简称USGS）处理的30米分辨率陆地卫星影像。

请注意，本矢量（vector）数据生成的面积统计结果可能与源栅格数据略有差异，这是由于生成矢量数据过程中所应用的数据转换与矢量清洗流程带来的偏差所致。

遥感影像通常由新南威尔士州规划与环境部（Department of Planning and Environment，简称DPE）常规采集，用于绘制植被清理分布图。本数据具备空间显式特性，可与其他数据集结合以识别单个地块上的相关活动。如需了解更多信息，请查阅隐私收集公告。
