Crops absorb some components of solar radiation which they use as a source of energy in the process of photosynthesis. The amount of near-infrared radiation that is reflected by plants is a good indicator of the condition and health of the crop. A healthy crop reflects most of the near-infrared radiation, whereas a crop under stressed conditions adsorbs this type of radiation. This information can be used for early warning detection of crop stress or failure. Unfortunately, the human eye cannot see in the near-infrared and crop stress in its initial phase is therefore often observed too late.
By using HiView’s near-infrared Flying Sensors imagery, early-warning crop stress can be detected over entire farms and fields. Combined with the ultra-high resolution and the precise timing of monitoring, a real early-warning system is available.
