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