Washington State Agricultural Land Use - 2022

This dataset contains crop information collected and stored for Washington. It consists of polygons representing individual crop field borders with attributes including crop, irrigation, survey date, TRS, county, source, cover crop, and acres. Attributes are updated by WSDA staff via ground surveys or by using remote sensing sources such as USDA's NASS Cropland Data Layer. Other sources include obtaining data directly from producers, using aerial or satellite imagery, and enlisting resources from Conservation Districts, etc. This land use data is published annually but is not updated in its entirety each year. WSDA strives to maintain a minimum 4 year refresh schedule for each geographic area with a target goal of every 2 years in dryland areas and 3 years in irrigated agricultural basins. For this reason, this dataset is not statistical, but it does provide an accurate snapshot of crops growing in each geographic area and provides trends over time. Since only one crop can be captured in a given space, double-crop systems cannot be captured. These systems are documented in the notes attribute and rotation crop attribute when confirmed. WSDA partners with USDA NASS and provides ground-truthed data for the Cropland Data Layer project, especially in areas not well represented by USDA FSA data.
