Typically capture the entire field in one image Imagery obtained may not be as frequent as desired or at critical times when imagery is desired During cloudy conditions, no images are available Lower imagery resolution compared with drones Capture large areas, therefore are better for landscape scale assessments Advantages and disadvantages of various sensor platforms. A summary of these regulations can be found at. Commercial flights include for-hire flights as well as flights in which the operator has a commercial/financial investment, such as commercial farming. After passing an airman knowledge test administered at Federal Aviation Administration approved testing centers ( ), a person can be licensed as a remote pilot and authorized for commercial flights. Regulatory changes by the Federal Aviation Administration, effective August 29, 2016, opened the door for widespread commercial drone flight. In many cases, growers may choose to contract for collection and processing of such data with a crop consultant or image service. Such systems are more costly to purchase and operate, and processing and analysis of such imagery requires skill and time. Georeferenced images can be used in geographic information system (GIS) software to relate multispectral imagery to other geospatial information, such as yield maps. Often such imagery is collected at regular intervals during the growing season to detect and help manage the onset of stress. Such systems involve sensors beyond standard RGB cameras, along with image processing, to generate maps of crop condition, or stress. The other end of the spectrum for current drone applications in agriculture is collection of georeferenced, multispectral images. Images from this type of use may or may not necessarily be archived after collection. Such systems are easy to operate by producers or crop consultants. A standard RGB camera may also be called a natural-color or true-color camera and will produce images similar to a digital point-and-shoot camera or smartphone camera. Such use can be accomplished with an inexpensive, off-the-shelf, consumer-grade drone with a standard RGB (red, green, and blue) camera. The ability to quickly view a field from above in real time can be an invaluable scouting resource to identify areas of concern. Many producers may be interested initially in use primarily for crop scouting with a system that has video feed to the ground control station. Use of drones in agriculture can vary widely. Agriculture is expected to be one of the largest markets for drones with a projected economic impact at over $32 billion globally (Michał, Wiśniewski, & McMillan, 2016). While commonly referred to as drones, these systems are more technically referred to as unmanned aerial vehicles (UAVs) or unmanned aircraft systems (UAS). There is great interest in the use of drones in agriculture.
