4. Pasture area fraction, 2000
Pasture Area fraction in 2000, obtained by combining agricultural inventory data and satellite-derived land cover data. The agricultural inventory data is used to train a land cover classification data set obtained by merging two different satellite-derived products (Boston University’s MODIS-derived land cover product and the GLC2000 data set).
