Fractional vegetation cover products for Queensland

Seasonal composites of fractional vegetation cover for Queensland since 1987, derived from USGS Landsat TM, ETM+ and OLI images. Also includes field data used for calibration and validation of fractional cover dataset (Star Transect Field Data). The data provided are 30 m resolution raster format images of land cover fractions (representing the proportions of green, non-green and bare cover) as well as two derived cover decile products at the same scale. The products are composited from single dates into representative seasonal images, for standard calendar seasons. The field data component constitutes 1500 Australia-wide sites. \r\n**Additional resources** \r\n- [Product Metadata - Seasonal Fraction Cover](http://qld.auscover.org.au/thredds/catalog/auscover/landsat/seasonal_fractional_cover/catalog.html) \r\n- [Product Metadata - Cover Deciles](http://data.auscover.org.au/xwiki/bin/view/Product+pages/Seasonal+Cover+Deciles) \r\n- [Product Metadata - Field Data](http://data.auscover.org.au/xwiki/bin/view/Product+pages/SLATS+Star+Transect+Data) \r\n- [Field data access help](http://data.auscover.org.au/xwiki/bin/view/Field+Sites/Access+Field+Data)

本数据集为1987年以来澳大利亚昆士兰州的植被覆盖分量季节合成产品，数据源自美国地质调查局（USGS）的陆地卫星（Landsat）TM、ETM+及OLI影像。本数据集还包含用于植被覆盖分量产品校准与验证的野外实测数据（星样带野外实测数据，Star Transect Field Data）。本次提供的数据包含两类内容：其一为分辨率30米的栅格格式土地覆盖分量影像，该影像表征了绿色植被、非绿色植被与裸地的覆盖占比；其二为同尺度下的两种衍生覆盖十分位数产品。上述产品均基于单景影像合成得到标准历法季节的代表性季节影像。其中的野外实测数据部分涵盖了全澳大利亚境内的1500个采样点位。
