Agricultural production is particularly sensitive to both environmental conditions and management practices. Furthermore, farmers are often confronted with large variations in soil moisture, plant nutrition, crop growth and crop yields due to terrain, weather, tillage, drainage and other factors. Fast crop canopy changes make continuous monitoring of crop canopy necessary (Schirrmann et al., 2016). It is thus critical that farmers know, in a timely fashion, where these variations exist in their fields in order to adjust their practices accordingly.
