The Normalized Difference Vegetation Index (NDVI) is an index of plant “greenness” or photosynthetic activity, and is one of the most commonly used vegetation indices. Vegetation indices are based on the observation that different surfaces reflect different types of light differently.

Quadcam Drones Ltd uses drone-based technology for monitoring crop health, with a primary focus on improving yield and reducing costs at commercial vineyards.


Grape producers can experience typical crop losses of 5-8%. New advancements in spectroscopy (capturing information in the entire color spectrum including non-visible infrared) in combination with drone technology enables growers and crop consultants to analyse an entire vineyard to assess plant health and detect problem areas more frequently and faster than currently possible. The ability to efficiently detect nutrient and water deficiencies as well as early onset of diseases, weeds, or pests will reduce yield loss and aid growers with the precision application of fertiliser, water, and other remedies where needed most. Crop analysis software used in conjunction with our autonomous aircraft collects data at regular intervals and transmits it to a cloud environment where the vineyard manager can consult the information on their tablet or smart phone. In summary we provide high definition NDVI maps that help grape growers maximize their vineyards potential.


Much of the data that growers need to improve their decision-making is made available with the right spectroscopy tools. This aerial imaging produces mapped data of plant health differentiated into colour bands.
