Corn, soybeans, wheat and rye fields across Brookings County, South Dakota, are mapped in 3D for 2022, 2023 and 2024. Each field shows its area, production in tons and value in dollars, while June 2024 NDVI, EVI2 and NDMI vegetation indices reveal crop health. Filters, dashboards and a storybook connect farm output with roads, population and rural settlements, a practical template for agronomists, agricultural lenders and precision farming teams.
