Mapping industrial poultry operations at scale with deep learning and aerial imagery [PDF]
arXiv, 2021 Concentrated Animal Feeding Operations (CAFOs) pose serious risks to air, water, and public health, but have proven to be challenging to regulate. The U.S. Government Accountability Office notes that a basic challenge is the lack of comprehensive location information on CAFOs.
