What satellites are used in Farm 360?

Farm 360 providess access to satellite images of the following constellations: 

Sentinel 2: is a constellation of 2 satellites managed by the  European Space Agency (ESA). It has the following features:

  • Resolution: 10mt
  • Revisit frequency:  5 days, in certain areas, every 2 to 3 days. 
  • Availability in Farm 360: since June 2015

Landsat 8:  is an earth observation satellite managed by NASA. It was launched in 2013 and has the following features:  

  • Resolution: 30mt
  • Revisit frequency: every 16 days
  • Availability in Farm 360: since May 2014

Resolution comparison between Landsat and Sentinel:


Spectral bands and monitoring index generation 

Both satellites capture images composed of different spectral bands. 

Thanks to the Farm 360 processing of the images ,the data provided by each band is combined in different ways, allowing to obtain multiple indices: NDVI, EVI, SAVI, NDRE (only on Sentinel), NDMI, NDWI y versions of the images in true color (TC) and false color (FC).

Each one of the indices is more appropriate for analyzing certain aspects of the crop cycle.

The more you are able to distinguish which index to use for each stage of the crop cycle, the better readings you can make from the satellite monitoring and the more accurate will be your approach to what is happening on the lot.
