We developed an object-based crop type ground truth dataset CropSight-US across the Contiguous United States for 2013–2023. Using satellite and street view imagery, we created an operational way to identify crop types and field boundaries without in-person surveys. This novel dataset provides reliable crop type ground truth with delineated field boundaries that can support large-scale crop monitoring and decision-making.
