Researchers have developed a new workflow to map farmland extent and boundaries using 1-meter NAIP imagery. The method combines a Residual U-Net model, trained with a Dice-dominant loss, and a Segment Anything Model (SAM 3) prompted with text. This approach achieved high accuracy, with the combined model showing significant improvements on challenging datasets like orchard rows and fragmented parcels. The resulting semantic farmland-extent layer can support agricultural monitoring where existing field maps are insufficient. AI
