The data is being used to calibrate, validate and improve vegetation fractional cover products derived from remote sensing, in particular the satellite sensors MODIS and Landsat. The data is being used to improve the national fractional vegetation cover product of Guerschman et al. (2009) derived from the Moderate Resolution Imaging Spectroradiometer (MODIS). This algorithm enables national, monthly identification of ground cover separating the photosynthetic and non-photosynthetic components by applying a linear unmixing methodology for spectral reflectance every 8 days as 16-day composites. For confidence in its ground cover estimates, the results were verified in the field at selected sites across Australia to allow more extensive calibration, validation and verification of accuracy of the remote sensing method. The Ground Cover Reference Sites Database represents the results of the field validation of remotely determined cover measurements by observing cover along point intersects with a total of 300 points (or 200 points with crops). It also has additional observations and measures such as landscape features, fire evidence, erosion evidence, biotic disturbance evidence, biomass estimates, basal area measurements, soil features and dominant vegetation species, as well as site photographs. The Ground Cover Reference Sites Database focuses on sites in extensive grazing systems of the rangelands and, to a lesser extent, in the mixed farming or intensive land use zone. Field validation aims at obtaining a wide spatial coverage of sites, with limited site revisits for temporal coverage. {"type": "Polygon", "coordinates": [[[130.464683726919, -33.7937054215798], [140.859961935671, -33.7937054215798], [140.859961935671, -27.0308423807193], [130.464683726919, -27.0308423807193], [130.464683726919, -33.7937054215798]]]} 130.464683726919 140.859961935671 -33.7937054215798 -27.0308423807193 Abutilon otocarpum Acacia aneura Acacia aneura var. aneura Acacia aneura var. tenuis Acacia ligulata Acacia murrayana Acacia papyrocarpa Acacia tetragonophylla Acacia victoriae Alectryon oleifolius Aristida contorta Aristida holathera Aristida sp.
