GFSAD Product Formats

NASA encourages use of Climate and Forecast (CF) Metadata Conventions.

Using CF conventions will enhance data discoverability, accessibility and usability.

Provisional Data DistributionGFSADCD1KM aka GCE V0.0

The GFSAD Global Crop Dominance at nominal 1KM(GFSADCD1KM), aka Global Cropland Extent 1km Crop Dominance (GCE V0.0), provides information on the spatial distribution of the five major global cropland types (wheat, rice, corn, barley, and soybeans), which occupy 60 percent of the total cropland area at nominal 1km. The map is produced by overlying the five major cropland types of the world produced by Ramankutty et al. (2008), Monfreda et al. (2008), and Portman et al. (2009) over the remote sensing derived global irrigated and rainfed cropland area map of the International Water Management Institute (IWMI; Thenkabail et al., 2009a, 2009b, 2011). The GFSADCD1KM product is an 8 class digital product that provides, at nominal 1 km, information on global: 1. Cropland extent\areas; 2. irrigated versus rainfed cropping; 3. Crop dominance; and 4. Cropping intensity (single, double, triple, and continuous crops).

Provisional Data DistributionGFSADCM1KM aka GCE V1.0

The GFSAD Multi-Study Global Crop Mask (GFSADCM1KM), aka Global Crop Extent (GCE V1.0), provides the spatial distribution of a disaggregated five class global cropland extent map derived at nominal 1km based on four major studies: Thenkabail et al. (2009a, 2011), Pittman et al. (2010), Yu et al. (2013), and Friedl et al. (2010). Classes 1 to Class 5 are cropland classes, that are dominated by irrigated and rainfed agriculture. Class 4 and Class 5 have minor/very minor fractions of croplands. GCE 1KM Multi-study Crop Mask is a 5 class digital product that provides, at nominal 1 km, information on global: 1. cropland extent\areas, 2. irrigated versus rainfed cropping. There is no crop type or crop type dominance information. Cropping intensity (single, double, triple, and continuous crops) can be obtained for every pixel using time-series remote sensing data.
