The monitoring of global cropland extent is critical for policymaking and provides important baseline data that are used in many agricultural cropland studies pertaining to water sustainability and food security. The GFSAD30AFCE data product uses two pixel-based supervised classifiers—Random Forest (RF) and Support Vector Machine (SVM)—and one object-oriented classifier—Recursive Hierarchical Image Segmentation (RHSEG)—to retrieve cropland extent from a combination of Landsat 8 Operational Land Imager (OLI) and Sentinel-2 MultiSpectral Instrument (MSI) data and elevation derived from the Shuttle Radar Topography Mission (SRTM) Version 3 data products. Each GFSAD30AFCE GeoTIFF file contains a cropland extent layer that defines areas of cropland, non-cropland, and water bodies over a 10⁰ by 10⁰ area. date: 2017-06 date_type: published publisher: NASA EOSDIS Land Processes DAAC place_of_pub: South Dakota, USA official_url: https://doi.org/10.5067/MEaSUREs/GFSAD/GFSAD30AFCE.001 citation: Xiong, J and Thenkabail, P S and Tilton, J C and Gumma, M K and Teluguntla, P and Congalton, R G and Yadav, K and Dungan, J and Oliphant, A J and Poehnelt, J and Smith, C and Massey, R (2017) NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) Global Food Security-support Analysis Data (GFSAD) Cropland Extent 2015 Africa 30 m V001.
