RECOGNIZE PEST INFESTATIONS AND DEFICIENCIES – In addition to visible light, multispectral cameras also record wavelengths in the near-infrared range (NIR band). With this, the “normalized differentiated vegetation index”, or NDVI for short, can be determined. The numerical values allow one to draw conclusions about how healthy the plants are. Once deficits have been detected in this way, they can be tackled in a targeted manner – by deploying a multicopter if need be.

Based on crop analyzes, the necessary pesticides can then be used in a targeted manner and disseminated using spray helicopters. In this way, resources are saved in two different ways, with the expensive materials only being used on the affected areas and working time being utilized efficiently. Even challenging locations, such as hillsides in vineyards, are no obstacle when it comes to deploying drones.

SEAMLESS ASSESSMENT POSSIBLE THANKS TO GPS – Agricultural areas can be predefined using a waypoint tool to ensure seamless surveying. A multicopter then flies off to each waypoint automatically. The data and images captured and evaluated in this way are the perfect foundation for the agriculture and forestry sector when it comes to making decisions on planning and budgeting.

FOR FIELDS, FORESTS, NATURE RESERVES – How healthy plants are can broadly be determined with the assistance of the NDVI index. An example of this is that bark beetle infestations can be detected in spruce forests because the crowns of affected trees show different IR reflections. Multicopters with NIR cameras detect the following: nutrient deficiencies, insufficient irrigation, pest infestations. Moreover, crop damage caused by wild boars can be detected and documented at an early stage from above.
