At A Glance
- Provides accurate data on acreage and crop type for all agricultural areas in the contiguous continental United States. This data may be used to address diet research questions related to food supply and production.
- Provides data used to generate agricultural production statistics and forecasts.
- Contains non-agricultural land cover data, such as urban infrastructure, forests, grasslands, and wetlands, which may be used in conjunction with the National Land Cover Dataset to inform comparative studies of geographic areas and obesity-related risk factors.
To collect data about crop-specific and non-agricultural land cover in the United States.
Farms within the contiguous continental United States.
Began in 1997. Conducted annually. Most recent year conducted was 2018.

Not a survey. Census by satellite.
Satellite imagery is collected from sensors maintained by USDA’s Foreign Agricultural Service, the U.S. Geological Survey and the National Aeronautics and Space Administration. Imagery is analyzed using a decision tree-based classifier, using USDA’s Farm Service Agency’s data and the National Land Cover Data dataset from the U.S. Geological Survey.
All states within the contiguous continental United States.
Detailed accuracy assessment tables are published within the official metadata files. The primary focus of CropScape is on large-area summer crops (e.g., corn, soybeans). Data on major crop types have been shown to have a classification accuracy of 85% to 95%. Non-agricultural land cover data are less accurate; researchers are encouraged to use the National Land Cover Dataset for studies focused on non-agricultural land cover.
