AE541: Applications of Unmanned Aerial Systems in Agricultural Operation Management: Part I: Overview

Figure 1. Patterns of NDVI (contrast between red and NIR wavebands calculated as [NIR - Red]/[NIR + Red]) scale the image between -1.0 (no vegetation) to +1.0 (full canopy with around three leaf layers). This image from a turfgrass operation in Hastings, FL shows variations of canopy closure in an early stage of development. Transitional regions between deep blue or red indicate variations between no vegetation (blue) to full canopy (red). Note artifacts in coloration around the truck parked at the northwestern corner of the image.
