Monitoring fields from the sky using drones produces an almost plant by plant inspection to determine different features of a crop. These can be used to recognise things like weed types, disease pressures, plant stress, crop damage, nitrogen requirements and yield potential. Drones can also fly low enough to get a very detailed look at the crop. Multispectral camera images are gathered to produce Normalised Difference Vegetation Index (NVDI) information.
Crop damage areas caused by fire or inclement weather can easily be surveyed and quantified for insurance claims.
