This map focuses on crop-specific land cover by identifying over forty crop categories and also includes major noncrop categories. The categorized Cropland Data Layer imagery shown on the map was produced by the National Agricultural Statistics Service (NASS) of the U.S. Department of Agriculture (USDA).
A decision-tree classification approach was applied using ground-truth data from NASS and the USDA Farm Service Agency; a combination of satellite imagery from Indian Remote Sensing Advanced Wide Field Sensor, and National Aeronautics and Space Administration Moderate Resolution Imaging Spectroradiometer sensors; and ancillary data sources.
