GFSAD全球耕地范围产品（GCEP）
NASA的 "研究环境中使用的地球系统数据记录"（MEaSUREs）全球粮食安全支持分析数据（GFSAD）数据产品以30米的分辨率提供了全球2015年的耕地范围数据。对全球耕地范围的监测对政策制定至关重要，并提供了重要的基线数据，用于许多与水的可持续性和粮食安全有关的农业耕地研究。GCEP数据产品使用基于像素的监督分类器--随机森林（RF），从Landsat 8 Operational Land Imager（OLI）、Landsat 7 Enhanced Thematic Mapper Plus（ETM+）和来自Shuttle Radar Topography Mission（SRTM）第3版数据产品的高程组合中检索出耕地范围。
