Satellite Monitoring Brazil’s Coffee Harvest
Combining Satellite imagery and GreenEye’s Patented Harvest Detection Method…
We’ve sampled terabytes of satellite imagery to derive the following projections for the current 2019 Brazilian Coffee Harvest.

Brazil's Satellite Derived Monthly Coffee Harvest
April 1st to August 31st 2018 Brazil harvested 51,107 Thousand 60 Kg. Bags of Green Coffee
April 1st to August 31st 2019 Brazil harvested 39,720 Thousand 60 Kg. Bags of Green Coffee
Brazil’s current 2019 Harvest is down 22.28% compared to the same harvest months of 2018.
Satellite Detected Farm Health
Brazilian Coffee Region NDVI
NDVI is an index ranging from -1 to +1 calculated based on the amount of Near Infrared and Red light reflected from an object. The graph above shows an average regional NDVI over time based on satellite imagery of Brazilian coffee farms. Notice how the NDVI peaks during the wet-season and decreases during the drier months when the coffee is harvested (April to October).
Healthy vegetation will have a high NDVI index as healthy leaves contain high amounts of chlorophyll which reflects Near Infrared light.
The graph shows a late March 2018 NDVI value of 0.76 and an early April 2019 value of 0.76. With this information one can infer that the farm region was roughly of the same level of health in the weeks prior to the 2018 and 2019 harvests.
Similar graphs can be made of particular farms of interest to monitor farm health over time. Visualizing this data geographically will also allow farmers to detect areas of their farm in need of attention. In the image below, the darker the shade of green, the healther that plot of farm land.
