**Delineate Anything Flow (DelAnyFlow)** is a resolution-agnostic methodology for fast, country-level agricultural field boundary detection from satellite imagery. It utilizes the **DelAny** instance segmentation model, which is based on a YOLOv11 backbone and trained on the large-scale Field Boundary Instance Segmentation-22M (FBIS 22M) dataset.

DelAny delivers state-of-the-art accuracy, showing significantly higher mAP and faster inference than alternatives like SAM2. It supports national-scale applications, having been used to generate a complete field boundary layer for Ukraine (603,000 km²) in under six hours.
