  "description": "Agricultural field polygons within smallholder farming systems are essential to facilitate the collection of geo-spatial data useful for farmers, managers, and policymakers.\nHowever, the limited availability of training labels poses a challenge in developing supervised methods to accurately delineate field boundaries using Earth Observation (EO) data.\nThis data set allows researchers to test and benchmark machine learning methods to delineate agricultural field boundaries in polygon format.\nThe large-scale data set consists of 439,001 field polygons divided into 62 tiles of approximately 5\u00d75 km distributed across Vietnam and Cambodia, covering a range of fields and diverse landscape types.\nThe field polygons have been meticulously digitized from satellite images, following a rigorous multi-step quality control process and topological consistency checks.\nMulti-temporal composites of Sentinel-2 (S2) images are provided to ensure cloud-free data.",
