NSW Foundation Spatial Data Framework - NSW SLATS LANDSAT Woody Change

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. This data describes the areas and type of woody vegetation\r\nchange (loss) based on the analysis of multi-date Landsat imagery covering NSW.\r\n\r\nThis data is based on a biennial LANDSAT coverage between 1988-2006 and annual coverage 2006-2010. LANDSAT Imagery 1988-2008 was processed by Geoscience Australia at 25m resolution.\r\n\r\n2008 onwards is based on USGS processed LANDSAT at 30m resolution. Note, 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.

本数据集源自用于生成2010年新南威尔士州（NSW）本土植被年度报告中年度化木质植被变化率的核心“SLATS 1988–2010年25米分辨率陆地卫星（LANDSAT）木质植被变化数据”栅格（raster）图层。该数据基于覆盖新南威尔士州的多期陆地卫星影像分析，描述了木质植被变化（减少）的区域与类型。

此数据采用1988-2006年每两年一期的陆地卫星覆盖数据，以及2006-2010年的年度覆盖数据。1988-2008年的陆地卫星影像由澳大利亚地球科学局（Geoscience Australia）以25米分辨率完成处理。

2008年及以后的数据基于美国地质调查局（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存在细微差异，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所带来的偏差。
