Using Satellite Imagery for Variable Rate Maps Curtis Dick
What Satellite Imagery is useful for • Designating Management Zones • Building Variable Rate Maps • Helping Identify Problems in Growing fields • Help identifying where to soil sample • Measuring Biomass
Satellite Imagery Technology • Agri-ImiGIS • Started in 1994 in North Dakota by providing satellite images for a variety of farming applications • Currently provide 2 types of images (both have NDVI capabilities) • Main use is for building management zones • Also provide products that allows producers to have access to the system via an app • The products allow for soil sampling and other practices to be tied into the imagery into a browser base
Landsat vs. Rapid Eye Landsat Rapid Eye
Major Uses in Oklahoma • A very successful use in Oklahoma has been with variable rate Growth Regulator in Cotton Production • The Images allow a producer or consultant to see the differences in a growing field • Landsat is updated every 16 days no matter if there is cloud cover or not • Rapid Eye takes 4-5 pictures during a growing season and will stay in an area until it gets a clear picture
Hard to tell in a growing field the amount of an input certain plants need
Drones • Around 140 different type of drones available for use • Prices range from $100,000 to $12,800 • As of right now primary purpose is for surveillance
senseFly • Switzerland based company that produces two types of Drones • Swinglet CAM • eBee
Are Drones Useful? Advantages Disadvantages • Are very easy to operate • Does not matter if it is cloudy • Can have an image of a field in 1 day • Do not fly well in winds over 25 mph • Are somewhat costly • If drones are being used commercially they can not be flown over 400 ft elevation in U.S.
Using Drones for Mapping NDVI Vs Green Seeker • Swinglet Cam • http://farmindustrynews.com/crop-protection/drone-plane-your-future-0 • Green Seeker
Review • Best use of satellite imagery seems to be to measure biomass • Satellite imagery is a useful tool in developing management zones, but should probably not be the only information the zones are based off of. • Drones for commercial purposes must be flown below 400ft.
