USDA Crop Sequence Boundaries

The Crop Sequence Boundaries (CSB) developed with USDA's Economic Research Service, produces estimates of field boundaries, crop acreage, and crop rotations across the contiguous United States. It uses satellite imagery with other public data and is open source allowing users to conduct area and statistical analysis of planted U.S. commodities and provides insight on farmer cropping decisions. NASS needed a representative field to predict crop planting based on common crop rotations such as corn-soy and ERS is using this product to study changes in farm management practices like tillage or cover cropping over time. CSB represents non-confidential single crop field boundaries over a set time frame. It does not contain personal identifying information. The boundaries captured are of crops grown only, not ownership boundaries or tax parcels (unit of property). The data are from satellite imagery and publicly available data, it does not come from producers or agencies like the Farm Service Agency.

Field boundaries for USDA CSB

Crop Sequence Boundaries (CSB) is a vector-based geospatial dataset which are fully synthetic representations of agricultural fields, their acreage, and cropping rotation history. These new data are primarily derived from a historical stack of Cropland Data Layers over a set time frame based on an algorithm of geospatial functions. It was developed in cooperation with the Economic Research Service.

Provides 16.194.865 field boundaries, based on data taken from taken from USDA CSB. Adjacent polygons with equal crops for 2023 have been merged ("dissolved") It has been converted to a fiboa GeoParquet file from data obtained from USDA.
