Adaptation and mitigation to climate change are key to ensuring global water and food security in the twenty-first century. In order to contribute to this humanity sustaining goal, the United States Geological Survey (USGS) produced the world’s first, Landsat Satellite-derived, global cropland extent product at 30m resolution (GCEP30) for the nominal year 2015 which is the highest resolution freely available global cropland dataset. The product was a result of a “paradigm-shift” in cropland production involving satellite sensor big-data analytics, machine learning, and cloud-computing on Google Earth Engine (GEE). The GCEP30 had an overall map accuracy of 91.7% with cropland class producer’s accuracy of 83.4% (errors of omission of 16.6%) and user’s accuracy of 78.3% (errors of commission of 21.7%). For the year 2015, GCEP30-derived global net cropland area was 1.873 Bha (~12.6% of the terrestrial area). The GCEP30 is downloadable at LP DAAC and viewable in full resolution here.
