I guess it IS rocket science!

Improving wine with satellites (ESA Portal) talks about how technology is being used in the vineyard.

"Earth observation satellites now have remote sensing instruments operating in a variety of modes, optical, radar, infra-red. The scientific data that can be extracted is considerable. Depending on the satellite's resolution, we can obtain data on precise soil composition, the slopes, exposure to sunlight, and the humidity of agricultural regions. With future satellites we will monitor how vineyards have been cared for during the year."
