A multi-spectral camera used in agricultures. It monitors subtle changes in the visible and near-infrared radiation that plants reflect. Growers use this data to spot plants under stress, monitor plant growth or to perform dozens of other functions helpful in managing crops. Variations in the near-infrared indicate changes to vegetation long before any indications appear in the visible spectrum. Can also be used in other fields such as biology, forestry, environmental research, surveillance, and infrastructure inspection.
