Multispectral aerial photography – is a modern cost-effective and time-saving instrument to estimate crop health .

It allows to inspect large areas and identify diseases of weeds, evaluate irrigation and as a result, increase its productivity and get a greater yield.

The multispectral sensors analyze specific bands of light reflecting off the leaves, reads the amount of light coming from the sun and amount of light reflecting off the crops. Ratio between these two values is called normalized difference vegetation index, that is a measure of plant health.

After data processing you receive vegetative index maps (NDVI, PVI, WDVI, SAVI, LAI and others) that indicate:

  • State of vegetation
  • Soil moisture content
  • Nitrogen content
  • Chlorophyll content
  • Biomass buildup

So you can make a comprehensive map of the field and optimize watering and fertilizing. As a result, you save time, costs and increase the efficiency of farming.
