Using satellites to improve wine

Physics Today
The Daily Telegraph : Growers are using powerful cameras on board a satellite 500 miles above Earth’s surface to take images of their vineyards, showing them where to plant vines and when to harvest the grapes.

The high-resolution pictures are so accurate they can calculate the number of leaves per square meter which is directly proportional to the quality and yield of grapes.Farmers will also be able to scan surrounding areas to see what land may be good for cultivation and so help the industry expand.The technology known as Oenoview is developed by Infoterra , a division of the European Aeronautic Defence and Space Company , and has already been used in various wine-growing areas of France.It works by calculating the density of foliage on vines by analyzing the light that reflects off them.
