More and more companies in the west coast Silicon Valley area of the United States are getting into agriculture technology development. A recent Fortune article mentions how companies from Google to Monsanto along with many other startups are jumping into the agriculture data realm.
UAVs are also part of the growth as part of the remote sensing umbrella for data acquisition according to MIT Technology Review. This article also mentions capturing weather data on field-scale levels. This will probably grow in the future with increased weather data that can be used for better future modeling with atmospheric and other applications.
