Cropland Data Layer
The Cropland Data Layer (CDL) is an annual, georeferenced, crop-specific land cover raster map covering the conterminous United States, produced by the USDA National Agricultural Statistics Service (NASS). It is generated from satellite imagery and extensive agricultural ground reference data, classifying each 30-meter pixel into crop types and other land cover categories. The CDL serves as an upstream source for KnowWhereGraph and supports agricultural monitoring, acreage estimation, and land use analysis.
