OVERVIEW: The Cultivated Layer is based on the most recent five years of CDL data (2019-2023). An Erdas Imagine Spatial Model is used to create the Cultivated Layer. The processing logic is as follows. If a pixel is identified as cultivated in at least two out of the five years of CDL data then it is assigned to the 'Cultivated' category. The exception is that all pixels identified as cultivated in the most recent year are assigned to the 'Cultivated' category regardless of whether or not they were cultivated in the previous four years of CDL data. 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.

ACCURACY: The accuracy assessment of the 2023 Cultivated Layer uses the same independent validation derived from the FSA CLU (agricultural categories) that was used to accuracy assess the 2023 Cropland Data Layer (CDL). See the 'Attribute Accuracy Report' section of this metadata file for the full accuracy report.
