Soybean iron deficiency chlorosis testing field site location near Danvers, MN. The field used in this study is located in Six Grove Township, MN (45.274285, − 95.718046) in Swift County. The yellow circles highlight the nine ground control points in the field for geometric calibration and the red squares highlight the radiometric calibration panels. These panels were painted with four levels of grey for empirical line method calibration. Overlaid to the field orthomosaic is a vector file delineating the plot boundaries of 3386 soybean plots. Each plot boundary is colored based on the trial each plot belongs to. A total of 36 trials was grown
