How healthy is your crop?

Live green vegetation absorbs visible light (solar radiation) as part of photosynthesis.  At the same time plants scatter (reflect) solar energy in the near infrared. Variations in plant health and growth have allowed us to generate the colored image below.

Greatly simplified, Green is healthy vegetation through to red which in this image represents bare earth, roads and the house roof. (apparently the gutters of the house roof don't need to be cleaned out just yet :-)
