<meta name="dc.description" content="The 2021 Cultivated Layer identifies cultivated and non-cultivated land cover for the Continental United States and is based on land cover information derived from the 2017 through 2021 USDA, NASS Cropland Data Layers (CDL). The Cultivated Layer is a raster, geo-referenced data layer that has a ground resolution of 30 meters. See the 'Process_Description' Section for details on how this data layer was created. For a more detailed description of the Cultivated Layer please reference the following journal article: Boryan, Claire, Yang, Z., and Di, L., 2012. Deriving 2011 Cultivated Land Cover Data Sets Using USDA National Agricultural Statistics Service Historic Cropland Data Layers. Proc. of IEEE International Geoscience and Remote Sensing Symposium, July 22-27, 2012, Munich, Germany. "/>
