The ukfields dataset is a publicly accessible Earth Engine asset of automatically delineated field boundaries spanning England, Wales, Scotland, and Northern Ireland.
This dataset was produced by Samuel Bancroft (University of Leeds) and Jake Wilkins.
The ukfields dataset contains field boundaries for the United Kingdom, derived from harmonic composites of Sentinel 2 imagery captured in 2021. The delineation process leveraged the Segment Anything Model (SAM) from Meta, ensuring efficient field segmentation at scale. The segmented fields have been masked to a 2021 Dynamic World composite of cropland.
The availability of accurate field boundary data is of high importance, especially in regions where such information is scarce. Releasing the ukfields dataset and the associated code is a step towards democratising access to parcel information over large geographic areas and serves as a blueprint for replicating similar efforts in other regions all over the world.
To access the ukfields dataset in Google Earth Engine, use the following asset path:
var ukfields = ee.FeatureCollection('users/spiruel/ukfields');
You can also download a fiboa GeoParquet from Zenodo.
