Applications for Drones in Agriculture

Type of imagery plays major role in desired applications Drone-Agriculture

Author: Nate Dorsey, RDO Equipment Co.

The June 2016 update to the FAA’s Part 107 regulations for flying drones is just one factor contributing to the increase of unmanned aircraft systems (UAS) use in several industries, including agriculture. But that’s only half of the story. As anyone in business knows, in order for a tool to make sense on a worksite, it first has to make sense on the bottom line.

In order to see a return from a drone investment on your farm, you need to know how to use a drone to save time, improve efficiency, and increase yields. Then, the real key to unlocking the true value of a drone comes from understanding the technology behind it.

Aerial Imagery
The high-quality images produced by drones are used for everything from pre-season scouting to monitoring crop health to identifying equipment issues. Drones produce three common image types:

Color (RGB)

-RGB images are similar to photos from a regular camera. They’re easy to understand, even for the novice drone user, but are the least descriptive of the three types.

Near Infrared (NIR)

-NIR provides images with higher levels of detail than those produced by RGB by utilizing color bands outside the light spectrum visible to the human eye.

Normalized Difference Vegetative Index (NDVI)

-NDVI uses both visible and near-infrared sunlight reflection to measure biomass (vegetation). Similar to NIR imagery, NDVI provides a higher level of detail than RGB images.

Each of these image types play an important role in the various applications for which drones are used.

Pre-Planning
The coverage area, vantage point, and speed a drone provides makes it a great tool for pre-season scouting. Using standard RGB imagery, the drone can produce 3D maps used for soil evaluations, topography reviews, and identification of drainage issues.

By gathering, reviewing, and evaluating this mapping data prior to planting, you only have a complete view of the whole area, but you may be able to identify problems and adjust planting strategy before, rather than during, the season.

In-Season Assessment
The primary advantage of drones over a manual scouting process is speed. An area normally monitored by a crop scout in several hours can be covered in a single, quick drone flight. This allows for one of the most common uses of drones in agriculture – ongoing monitoring of crop health throughout the season. NIR imagery is most valuable in this process for several reasons.

First, NIR images show heat so they can easily identify areas of plant and water stress. Their high level of detail offers additional applications such as weed detection, defining management zones, evaluating effectiveness of ponding and water management, and quantifying machinery-induced crop limiting factors. This ability to identify concerns and intervene quickly is directly linked to a better year-end harvest.

There are uses for RGB images in-season as well. They’re often used to identify planter skips and evaluate areas of lost production, allowing you to correct the problems.

Long-Term Analysis
In addition to their immediate help before and during the season, drone use can be beneficial over long periods of time. Like RGB and NIR, NDVI images can also show ponding, help assess crop vigor, and show changes in field conditions over time.

NDVI images measure the amount of biomass or “greenness” of a plant and create an index, which is then compared to areas of less vegetation and more vegetation. The numbers range from -1 to +1, with high amounts of biomass and green vegetation having increasingly positive numbers.

NDVI values are very sensitive to anything that affects light, such as haze, clouds, or even soil. For this reason, NDVI images are most effective in optimum conditions.

Bottom line: A drone is a helpful tool that can provide quality data and images but it’s up to you to analyze data and use it to make the best decisions for the crop and your farm.

FAA Part 107 Test Info

Three things to know to prepare for your test RDO_Integrated_Controls

Author: RDO Integrated Controls

The Federal Aviation Administration’s (FAA) new small drone rule –known as Part 107 – went into effect on August 29. If you’re confused by what Part 107 means to you, we’ve provided three key components to help make sense of it:

Understand the process.
The FAA clearly describes what to expect if you are an existing FAA Pilot or if you are starting from scratch.

Free study materials online.
Sharpen those pencils! The FAA has a great online, free study material guide. You can also take the online course and even take a sample exam at the end.

Just Finalized: FAA Part 107 Rules for Flying Drones

What does this mean and what’s next? FAA-Part-107

Author: RDO Equipment Co.

On June 21, the FAA announced that Part 107 Rules for UAS (Drone) Operations in the National Airspace have been finalized.

The name of the operator’s certificate required is “Remote Pilot’s Certificate” and clients will need one to fly with Part 107 or their Exemption.

However, the new rules will not be implemented for 60 days, presumably in late August. Until then, you may consider the current operating rules unchanged, and use this window as a time to prepare.

Overall, this announcement has great benefits for the use of UAVs in agriculture, civil engineering, aggregate, and mining industries. Becoming compliant to fly commercial UAVs will be more accessible for many companies.

Here are the highlights from today’s announcements:

Getting the Part 107 Remote Pilot Certification for non-FAA Pilots

  • You may begin the Part 107 Remote Pilot Certification training online.
  • You may take the Knowledge Exam at an FAA testing Center once the Rule is implemented.

Getting Part 107 Remote Pilot Certification for current FAA Pilots

  • You may begin the Part 61 additional Remote Pilot Certification training online.
  • You do not need to take a Knowledge Test at a testing center, but must complete the online training course .

Current 333 Exemption Holders

  • Your FAA Pilot must complete the online Remote Pilot Certification training online before the implementation of Part 107.
  • Your 333 Exemption is still valid per the time period stated on it.

Pending 333 Exemptions

  • You will be notified by the FAA that you are in one of three tiers and be given options to continue or transfer to Part 107

TSA Approval

  • You will be required to be approved and vetted by the TSA in order to fly with a Remote Pilot Certification.

What are the final rules?

  • The FAA has posted a summary and a complete overview of the final rules, which will be implemented later this summer.
