2) A digital surface model of the same field. “Look at how clear the pivot tracks are compared to the orthomosaic,
3) This crop surface map of full-canopy corn was generated from the UAV-sourced .las format DSM; blue shows the tallest corn, orange shows bare earth.
4) Topography: Purple shows highest ground, red lowest.
5) Relative biomass map of the field. In red in the lower-left corner, and the gravel ridges running through the field have resulted in shorter corn, evidenced by the light to dark-green streaks running diagonally.
6) Management zones, derived from many sources of data, delineate yield potential. The red areas have the lowest yield potential, the purple areas the highest.
