Life's but a walking shadow | Quote:" Descartes says it analyzes satellite data of every single farm in the US on a daily basis (provided there is no cloud cover) and updates its corn yield prediction every two days."

For example, they may have had a suspicion that South Dakota was going to drought out but until it happen even they didn't know. |
