The GFSAD products are derived\nthrough multi-sensor remote sensing data (e.g., Landsat, MODIS, AVHRR),\nsecondary data, and field-plot data and aims at documenting cropland\ndynamics.\n\nAt a nominal 1km scale, V0.1 provides the spatial distribution of a\ndisaggregated five-class global cropland extent map derived from four\nmajor studies: Thenkabail et al. (2009a, 2011), Pittman et al. (2010),\nYu et al. (2013), and Friedl et al. (2010). V1.0 is a 5-class product that\nprovides information on global cropland extent and irrigated versus rainfed\ncropping. There is no crop type or crop type dominance information. Cropping\nintensity (single, double, triple, and continuous crops) can be obtained for\nevery pixel using time-series remote sensing data. The GFSAD1000 nominal\n2010 product was created with data from 2007 to 2012.\n\n### Bands\n\n\n**Pixel Size**\n\n1000 meters\n\n**Bands**\n\n| Name | Min | Max | Pixel Size | Description |\n|-------------|-----|-----|------------|------------------------------|\n| `landcover` | 0 | 9 | meters | Crop mask class descriptions |\n\n**landcover Class Table**\n\n| Value | Color | Description |\n|-------|--------------|------------------------------------------|\n| 0 | black | Non-croplands |\n| 1 | orange | Croplands: irrigation major |\n| 2 | brown | Croplands: irrigation minor |\n| 3 | darkseagreen | Croplands: rainfed |\n| 4 | green | Croplands: rainfed, minor fragments |\n| 5 | yellow | Croplands: rainfed, very minor fragments |\n\n### Terms of Use\n\n**Terms of Use**\n\nMost U.S. Geological Survey (USGS) information resides\nin the public domain and may be used without restriction.
