    What Is Precision Agriculture?
    Precision agriculture is a farming administration idea primarily based on observing, measuring, and responding to inter-and intra-field variability in crops.
    The aim of precision agriculture is to extra effectively apply a farm’s restricted sources to realize most yield. A major technique for doing that’s to attenuate the variability of crop well being inside and throughout fields. To be taught extra about precision agriculture, learn this glorious overview printed by The Economist.
    Due to its nature, precision agriculture requires a LOT of knowledge to work. The three fundamental varieties of knowledge embrace:
    geo-tagged photos: seen and multi-spectral aerial photos taken of fields, over time; that is the place drones play
    gear efficiency: real-time suggestions & logs supplied by sensor-equipped manned and unmanned gear akin to seeders, spreaders, tractors and combines
    administration knowledge: crop yield and different knowledge supplied by farm operators
    The use of precision agriculture applied sciences is rising very rapidly, globally, based on Technavio.
    Where Do Drones Fit in Precision Agriculture?
    Drones are actually simply a brand new, high-precision approach to get hold of geo-tagged photos from the air.
    Compared with different aerial survey strategies, drones generate extra exact and extra frequent knowledge concerning the situation of crops. This knowledge is utilized in some ways to enhance the efficiency of a farm’s operation.
    For surveying fields of lower than 50 hectares in measurement, drones are cheaper than manned plane surveillance, manned scouting, and satellite tv for pc imaging.
    Some declare that the new FAA guidelines will prohibit the usefulness of drones for agriculture as a result of, underneath the brand new Part 107 guidelines, all remark and measurement should be taken by a drone that’s throughout the visible line of web site (VLOS) of the operator. This turns into an actual challenge for fields and farms which can be larger than VLOS.
    But the overwhelming majority of farms don’t have this downside.
    According to this report, there are roughly 2.1 million farms in America. The common measurement is 434 acres. Small household farms, averaging 231 acres, make up 88 %, that means that 1.85 million farms can profit instantly from ag drones.
    Drones are used to collect quite a lot of image-based knowledge concerning the situation of crops, fields, and livestock – together with:
    plant peak
    plant rely
    plant well being
    presence of vitamins
    presence of illness
    presence of weeds
    relative biomass estimates
    3D / volumetric knowledge (piles, patches, holes and hills)
    For livestock operations, drones may be used to observe the placement, standing and motion of animals over time with extra frequency and at a decrease value than different means.
    Drone knowledge is used to do farming jobs extra successfully and effectively, together with:
    Crop Scouting – substitute males with drones
    Crop Health Monitoring – largest ROI, by far
    Field Surveying/Scouting (earlier than planting)
    Nitrogen Recommendation
    Yield Monitoring
    Plant Stress Monitoring
    Drought Assessment
    Senescence Analysis
    Leaf Area Indexing
    Phenology
    Tree Classification
    and extra
    To take fast motion, orthomosaic photos generated by drones may be fed into an agricultural program like SMS by Ag Leader, SST Summit®, FarmCeremony®, Stratus®, Sirrus®” or different software program instruments to create prescription maps.
    Prescription maps inform the farm operator the place & what particular actions are wanted, akin to growing or reducing nitrogen unfold on bother spots. Prescription maps may be transferred straight right into a precision applicator (sprayer) like a John Deere® or Case IH®.
    Here’s an ideal 7-minute video section produced by Iowa Public TV that explains why an increasing number of farmers are incorporating drones into crop administration.
    Drones & Agronomy Management Systems
    Because of the quantity of knowledge required, many precision farmers use agronomy administration methods to gather and combine all the knowledge flowing to/from their sensor-equipped tractors, combines, drones and different gear discovered on farms right now.
    Leading agronomy administration platforms embrace AgOS by AgWorks and MyAgCentral.
    Drones work together with agronomy administration methods by feeding them with wealthy, detailed and well timed geo-tagged photos. Using this knowledge, farmers can react extra rapidly and extra exactly than they’ll utilizing different aerial imaging strategies.
    Drone Advantages Over Other Aerial Imaging Systems
    By some measures, 80% of the worldwide drone trade revenues are associated to agriculture, indirectly.
    But why would farmers – a number of the most risk-averse individuals on Earth – undertake such a brand new expertise?
    Perhaps it’s as a result of agriculture drones provide clear benefits over different crop monitoring strategies together with satellite tv for pc imaging, manned scouting, and manned plane. These benefits embrace:
    Cheaper Imaging: for fields lower than 50 hectares in measurement, drones are significantly inexpensive than satellites or manned plane surveillance.
    Greater Precision: drone cameras take centimeter-level photos that reveal far more element a couple of crop’s situation.
    Earlier Detection of Problems: as a result of drones survey extra regularly, weeds, pests and different abnormalities are detected earlier.
    Total-Field Scouting: as an alternative of driving an ATV across the perimeter to scout maybe 5% of a area, now each area may be scouted 100% utilizing drones.
    3D/Volumetric Data: drone photos can be utilized to calculate the amount of piles, holes, hills and patches. These may be in comparison with Infrared photos to detect density points like scorching spots in a crowded beet area, or to establish contour issues akin to north slope shade points.
    More Frequent Index Reporting: drones provide a cheap approach to monitor crops extra regularly for key indices like CCCI (cover chlorophyll content material index), CWSI (crop water stress index) and NDVI (normalized distinction vegetation index).
    In day-to-day operations, these benefits assist farmers catch issues sooner and react extra rapidly, which might save 1000’s of {dollars} in crop losses per area.
    Long-term, the info generated by drones assist farmers achieve a extra correct & detailed image of how their crops are reacting to their administration methods, which might result in simpler use of restricted sources.
    After all, a typical household farmer solely will get 40 probabilities (seasons) to get issues proper… each additional bit of information helps!
    How Flying Cameras Measure Crop Health
    Most agriculture drones depend upon multi-spectral imaging to identify issues with a crop’s well being; particularly, they take a look at modifications over time in seen mild (VIS) and near-infrared (NIR) mild mirrored by crops. These photos are taken over time by drones, manned plane or satellites.
    It is feasible to detect plant well being from these photos as a result of crops replicate completely different quantities of seen inexperienced and NIR mild, relying on how wholesome they’re. By measuring the modifications in seen and NIR mild mirrored from a crop, we are able to spot potential well being points.
    This picture explains the overall concept:

     
    To monitor modifications in plant well being over time, drone photos are processed to calculate a monitoring index referred to as NDVI (normalized distinction vegetation index), which is a measure within the distinction between mild depth mirrored by the sphere in two completely different frequencies:
    NDVI is the ratio of close to infrared (NIR) reflectivity minus seen pink reflectivity (VIS), divided by NIR plus VIS:
    NDVI = (NIR-VIS)/(NIR+VIS)
    Here is what you see while you evaluate a traditional digicam picture of a winter wheat area to a NDVI-processed picture of the identical area:
    VIS and NDVI photos of winter wheat area (courtesy Agribotix)Notice how the NDVI-enhanced picture (proper) does an ideal job separating the wholesome wheat stalks (inexperienced) from dying edges (pink) and the dry earth (black/brown).
    There is a few debate over whether or not NDVI is the fitting index or whether or not the straightforward distinction between mild spectrums (NIR – VIS) is extra helpful.  Agribotix put collectively a nice writeup on this debate and the misconceptions re. what NIR recognizing can and can’t do right now.
    NDVI is the preferred index calculated utilizing drone knowledge, however there are numerous others. Some could also be roughly necessary to your farm, relying in your state of affairs. Some of the extra fashionable indices embrace:
    CWSI (crop water stress index): measures temperature differentials to detect/predict water stress in crops. Requires a thermal imaging sensor and the usage of a close-by climate station.
    CCCI (cover chlorophyll content material index): detects cover nitrogen ranges utilizing three wavebands alongside the pink fringe of the seen spectrum. Requires seen and near-infrared cameras.
    If you need to dive deep into this rising science of agriculture picture processing, right here’s a listing of the newest analysis.
    First Decision: Fixed Wing or Multi-Rotor?
    AgEagle RAPID – flying over areaFixed wing drones just like the AgEagle RAPID, PrecisionHawk Lancaster and SenseFly eBee SQ are sometimes most well-liked by farmers as a result of they’ll cowl extra space and spend extra time within the air than a multi-rotor platforms just like the DJI Phantom 4.
    That stated, they’ll’t do every thing and are finest fitted to giant, open-field scanning.
    Fixed wing drones typically carry extra payload than a multi-rotor – which suggests extra sensors – so extra info may be captured in a single flight. This can scale back the overall time to gather knowledge for a given acre.
    Fixed wing drones are dearer, too – they usually value $5,000 to $25,000 or extra, after being fitted with sensors.

    Multi-rotor ag drones like DJI’s Matrice 100 are better-suited to precision imaging of small/constrained areas and 3D scanning of fields and objects, attributable to their maneuverability.
    Flight instances for quads and different multi-rotors are about 1/2 that of a fixed-wing drone.
    Payloads on many multi-rotors are lower than fastened wings, so most solely carry one or two sensors. As a end result, masking a whole area can take twice so long as with a fixed-wing.
    Multi-rotor drones are usually cheaper than fastened wings, beginning at round $1,500-$10,000 for a professional-grade digicam drone packaged with multi-spectral cameras and software program for agriculture picture processing.

    Rather than choosing one sort of drone, some farmers and operators buy inexpensive variations of each.
    A hard and fast-wing drone is used for giant open areas the place lengthy, unobstructed straight-line passes are potential; and, a small cheap multi-rotor is used for spot-checking bother areas extra intently, for fast scouting missions and for dealing with space a aircraft can not fly over.
    Lots of farmers right now begin by shopping for a ready-to-fly $1,500 quadcopter like a Phantom 4 PRO or an NDVI-equipped pre-tested answer like DJI’s Smarter Farming Package.
    After testing the ROI of drone surveying, they might improve to the dearer and extra environment friendly multi rotor and fixed-wing packages that may combine with their Farm Management Information Systems (FMIS) and Agronomy Management Systems (AMS).
    Capturing The Data: Imaging & Sensors

    There are many decisions of imaging sensors out there right now for agriculture drones. Options vary from $200 for a GoPro HD digicam to effectively over $50,000 for a hyper-spectral digicam.
    Cameras
    Horizon Precision Chroma – digicam and gimbalThe most typical and least expensive sort of sensor is a high-resolution digicam, which takes seen wavelength photos (VIS). Several of those cameras may take near-infrared photos (NIR) when outfitted with the fitting filters.
    The minimal picture decision required for agriculture functions is 12 megapixels, which fashionable drone cameras such because the GoPro Hero 3 and Hero 4 are able to capturing.
    In distinction to what most photographers will inform you, you need a digicam with a wide-field, wide-angle or “fish-eye” lens, as these lenses are likely to seize extra space in a single shot.  Don’t fear concerning the picture distortion – high quality picture processing software program eliminates this throughout processing.
    Some of the extra fashionable cameras utilized in agriculture right now embrace:
    Sony QX1: compact, light-weight mirrorless digicam takes 20 megapixel excessive precision Images in RAW and JPEG. VIS photos solely.
    Canon EOS Rebel SL1 DSLR Camera Kit: captures VIS photos solely.
    Zenmuse X7: Gimbal and digicam system used on DJI methods. VIS photos solely.
    GoPro Hero: light-weight and weather-proof, GoPros are used on lower-cost quadcopter drones. The Hero in all probability the preferred ag digicam in use right now. VIS photos solely.
    MaxMax provides a line of Nikon, Sony and different mannequin near-infrared (NIR) cameras priced from $500 to $5,000. NIR and VIS variations.
    Multi-Spectral
    MicaSense Red multispectral sensorMulti-spectral imaging sensors help you see belongings you can not see within the visible spectrum, akin to moist patches on the bottom.
    The MicaSense Red multi-spectral sensor (proven above) lists for $6,450.
    Another choice is the Sentera NDVI improve for the DJI Phantom collection drones. This is a brand new ultra-lightweight NDVI sensor for Phantom 3 and Phantom 4. The DJI gimbaled digicam is just not modified. It captures visual-band (VIS), near-infrared (NIR), and NDVI knowledge collectively throughout a single flight.
    Thermal
    Thermal Sensors can detect moist vs. dry soilAirborne thermal sensors can see hotspots and measure modifications in land and plant temperature over time.
    Thermal sensors may detect the presence of water attributable to its cooling impact, which may be useful in recognizing crop harm attributable to drought and/or seasonal points.
    LIDAR
    LIDAR imaging can detect elevation modifications & drainage issuesLIDAR is a exact distant sensing expertise that measures distance by illuminating a goal with a laser and analyzing the mirrored mild.  LIDAR is often used to measure buildings and land plenty with precision, and to develop an correct 3D mannequin of an space.
    LIDAR sensors are very costly, typically costing $60,000 to $150,000.
    Surveying Crops By Drone: The Process
    Whether you employ a hard and fast wing or a quad to survey your fields, the method of gathering helpful knowledge with a drone consists of 4 primary steps, as follows:
    1. Plan Your Flight

    Many of the newest agriculture drones include flight planning software program that lets you to attract a field across the area you need to survey (on a Google Earth map or related), and a flight plan will probably be created for you routinely. Some even plan the digicam photographs for you, routinely.
    Then, you add the flight path into your drone and prepare to fly.
    If you’re utilizing a home-built platform or an older floor management station, then it’s possible you’ll must manually code or set every flip level.
    2. Fly & Shoot

    With your flight plan loaded and drone armed, it’s time to start out flying – and capturing photos.
    With a fully-integrated system just like the PrecisionHawk Lancaster, this half is simple.
    Basically, you simply ship the drone on its means and the system will routinely take photos utilizing the onboard digicam and sensors because the drone executes its flight path. The drone will use GPS location to set off every shot.
    After ending its run, the drone lands routinely (often all goes effectively). Easy!
    If you don’t use a very built-in drone package deal, then one individual will must take the photographs manually whereas a GPS autopilot or one other pilot flies the plane.
    If you’re manually capturing your photos, please bear these factors in thoughts:
    to seize excessive decision knowledge accurately for ag functions, your photos want to overlap with one another by at the very least 70%
    shoot photos primarily based on GPS location, not time, to make sure you get the picture overlap and the protection wanted
    3. Process Images
    The most difficult a part of the agriculture drone surveying course of is translating the a whole lot of high-res photos you simply captured into info you’ll be able to truly use. But don’t fear, it’s not that tough to do (or be taught).
    Most farm drone operators must course of a whole lot of visible, thermal and multi-spectral photos per flight, to establish modifications in crop well being over time or to identify anomalies.
    All of those photos should be stitched collectively, transformed into orthomosaic 2D photos, processed and analyzed so that you can get helpful info from the flight.
    Aerial drone photos captured & prepared for stitchingThat’s a number of knowledge processing. And your own home PC in all probability isn’t as much as it.
    This is the place picture processing software program and providers are available.
    Popular Image Processing Software for Agriculture
    Most agriculture drone operators use the next instruments to show aerial photos into helpful knowledge. All of them use cloud-based processing to take the load off of you:
    Pix4D: this fashionable & costly picture processing platform converts a collection of aerial photos into 2D orthomosaics, 3D level clouds and 3D mesh fashions. Pix4D may calculate NDVIs, DVIs, SAVIs and customized indices as wanted. To use Pix4D, you add your photos, allow them to course of, then obtain your reviews and visuals usually inside minutes to a couple hours.  Pricing is $350 per thirty days to hire or $8,700 to personal.

Performs aerial triangulation (AT) and produces dense digital floor fashions (DSM), digital terrain fashions (DTM), level clouds, orthomosaics and vectorized 3D fashions.
    senseFly eBee Ag: extracting NDVI knowledge from photosSome picture processing platforms are proprietary to the flying {hardware} you’re utilizing, and others are common objective instruments that anybody can use. General-purpose packages like Pix4D are likely to have a little bit of a studying curve.
    Image Processing Services for Agriculture
    If you don’t need to function the software program your self, you’ll be able to add your knowledge to a knowledge processing service who will generate the reviews for you.
    4. Review & Take Action
    Now that you just’ve downloaded your reviews and enhanced photos, it’s time to see what’s up together with your crops.
    Perhaps you’ll see points your scouting crew couldn’t see from the bottom:

    Or, possibly you’ll discover an issue with water retention after the newest storm:

    Or, maybe you’ll uncover new bother spots in your corn fields that want a bit extra nitrogen:
    DVI photos of 40 acres of corn (courtesy Agribotix)Whatever you discover, after you’ve reviewed the well being of your crops you’ll be able to enter the info into considered one of a number of farm administration methods like MyAgCentral to enhance your total view of the farm’s well being and operational standing.
    And take motion.
    How Much Does It Cost To Survey My Farm?
    Agris Co-op Ltd. in Chatham, Ontario is among the first precision ag drone imaging service suppliers to enter the Canadian market.
    Measure.aero’s Cost Estimator softwareUsing fixed-wing eBee and Swinglet drones, the agency shoots high-res NDVI photos of corn fields in Ontario for a value of about $5 an acre. A single flyover covers 100 acres in 15 minutes, capturing about 300 photos for a value of $500.
    This compares to a price of about $1,500-$2,000 for satellite tv for pc or manned plane pictures of 100 acres, or $15-20 per acre; and, each these older strategies yield much less decision, may be hampered by cloud cowl, and take extra time to course of the photographs.
    On a single day, Agris can cowl greater than 1,000 acres utilizing a single drone. Images are post-processed in about 2 days.

    Options and Upgrades
    Without going into element, you ought to be conscious that a few of your system’s parts may be upgraded or changed if you happen to don’t like what you’re at the moment utilizing.
    The most typical parts upgraded embrace:
    Ground Control Station
    RC Controller
    Sensors
    Props
    Avoid altering picture processing instruments and providers which were designed together with your {hardware} in thoughts.  Something to consider when deciding on your first drone.
    Common Issues and Concerns
    Flying a drone for agriculture entails most of the identical points going through shopper and different industrial drone operators. But there are a couple of gotchas distinctive to agriculture, particularly relating to knowledge and the EPA.
    Privacy Laws
    There’s a number of noise within the media right now about digicam drones taking pictures of individuals with out their data. Shotguns have been used to settle the rating.
    While this might occur on a farm, it’s unlikely.
    Nevertheless, your neighbor’s residence and fields are their property, and taking unauthorized photos of them may violate native or state privateness legal guidelines. And state legislatures are on fireplace, relating to drones.
    Nineteen US states (Arkansas, Florida, Hawaii, Illinois, Louisiana,Maine, Maryland, Michigan, Mississippi, Nevada, New Hampshire, North Carolina, North Dakota, Oregon, Tennessee, Texas, Utah, Virginia and West Virginia) have handed laws. 6 different states have adopted resolutions.
    In 2015 alone, 45 states have thought of 156 payments associated to drones.
    So: be sure you test with an area lawyer to get the newest guidelines in your area.
    Connectivity and Bandwidth
    Millions of acres of farmland within the US have little to no on-line connectivity or cell protection. If this consists of a few of your fields, then you want the capability to retailer captured photos & knowledge regionally – in the drone or on a close-by floor station – after which add them afterward, while you get again to the workplace.
    Systems akin to AgOS by Agriworks function underneath the belief it’s possible you’ll not have connectivity always.
    Don’t select a drone that requires a dwell connection to the web to seize knowledge; it simply isn’t a good selection for agriculture.
    Data Ownership
    The picture knowledge generated by agriculture drones may be actually helpful for many individuals aside from farmers.
    The EPA, county officers, drone operators, land surveyors and land administration officers can get an amazing quantity of worth out of your geotagged photos – if they’ve entry to them.
    Some organizations may do harm to a farm if they’ve entry.
    For this purpose, possession of knowledge is a important authorized challenge that must be handled upfront, through contract, everytime you:
    rent somebody to carry out an aerial survey of your farm
    course of your photos by means of a 3rd celebration (software program or service supplier)
    share or commingle your photos with a 3rd celebration
    By default, the farmer/land proprietor ought to at all times retain full possession of all knowledge generated by drones flying over his/her property. Then, through contract, these rights may be granted to 3rd events on a must know, exception foundation.
    Bottom line: you by no means need a third celebration to personal your knowledge.
    FAA Regulation & Operator Certification
    Flying drones for agriculture is at all times a industrial operation, based on the FAA.
    By regulation, your drone operator will need to have FAA operator coaching and have their distant pilot certificates earlier than they’ll function a drone over your land.
    If they aren’t correctly licensed to fly an unmanned plane, then you shouldn’t rent them nor allow them to function a drone over your property – even when no cash modifications arms.
    EPA Regulations
    By regulation, the EPA has the fitting to entry any and all knowledge generated by drones flying over your property.
    There’s nothing you are able to do about this. For this purpose, knowledge retention and storage insurance policies are necessary to concentrate to.
    Interference With Other Aircraft
    Crop spraying and different manned plane might share the identical airspace as an agriculture drone.
    For this purpose, you will need to file a flight plan together with your native airport/FAA workplace earlier than each drone flight.
    Make certain your drone operators perceive this, too.
    Get Your Contracts Right
    If you’re a new agriculture surveyor or drone operator, then you definitely want skilled authorized assist when establishing your contracts to take care of the problems above (and extra). DroneRegulation.Pro provides operators contract templates, coaching movies and a novel “Ops In A Box” enterprise setup package.
    If you use a farm and are focused on hiring a drone surveyor, then be sure you know what a very good contract appears to be like like. 
    We’re Still In The First Season…
    Little recognized truth: Japan has been utilizing unmanned aerial drones for over a decade, in rice farming.
    But within the US & Canada, agriculture drones are very new.
    In truth, the first FAA exemption for a precision agriculture drone operator was solely awarded in January of 2015.
    And based on that operator, Empire Unmanned, solely 5-10% of farms are utilizing drones of their precision agriculture operation.
