UAV Helicopter Drones In The News

FAA Releases Small UAS Notice of Proposed Rulemaking! - Check out the provisions being proposed in the FAA’s Small UAS NPRM.

FAA Grants UAV Permits for Agriculture & Real Estate Companies - The Associated Press reports that on Tuesday, the FAA issued exceptions to the commercial UAV ban, permitting the monitoring of crops and real estate use for aerial photographs of properties for sale. This is the first time permits have been granted to agriculture and real estate companies.

FAA Poised to Include Limitations on Hobbyist UAVs - The FAA is proposing to amend its regulations to adopt specific rules for the operation of small unmanned aircraft systems (UAS) in the National Airspace System (NAS). .

Judge Rules Against FAA in ‘Landmark’ UAV Challenge -  In a decision dated March 6, NTSB Judge Patrick Geraghty found that the FAA has no regulations that apply to model aircraft or that classify a model aircraft as an unmanned aircraft system.

UAV FAA Regulations For more than five decades, the Federal Aviation Administration (FAA) has compiled a proven track record of introducing new technology and aircraft safely into the National Airspace System (NAS).

FAA Fact Sheet – Unmanned Aircraft Systems (UAS) - For Immediate Release.

FAA Certificate of Authorization or Waiver (COA) - Before you can operate a UAV in National Airspace System (NAS) you must have a COA. The average time to issue an authorization for non-emergency operations is less than 60 days,

NDVI Explained

A simple overview of how drones are used in the farming industry to provide aerial imagery to create NDVI maps to improve crop yields, reduce farming costs, protect the environment and quantify crop damage insurance claims

The FAA recognizes that drones are essential to increasing the productivity of farmlands. Small drones pose a limited risk of injuring people, other aircraft, and property. Thus FAA approval to use drones for farming is coming soon.

Probable FAA policies will revolve around safety, primarily collision avoidance.

  • Daylight operation
  • LOS (Line of Sight) Operation
  • 400' Ceiling
  • Various safety devices, pilot and aircraft certifications, training, safety protocols, etc.

Agronomists using drones to assist their recommendations for fertilizer and pesticide application can improve the bottom line to farmers by as much as 15%, and help the environment as well.

The world's farmers must increase yields to feed the world's rapidly growing population. Drones are the latest technological advancement to assist in increasing crop yields while lowering pollution and costs.

Large fields and tall crops are extremely difficult to assess from the ground. Drones provide aerial access at a relatively low cost.

Agronomists operate the drones themselves or hire local drone service providers to fly the fields.

Normalized Difference Vegetation Index (NDVI) is an extremely important tool to determine if crops are stressed. NDVI compares bands of light to accurately determine plant stress. This is state of the art technology. Wikipedia explains NDVI in detail.

Photos directly from the onboard NDVI compatible camera are unusable as is. The photos must undergo special processing.

First, individual photos are stitched together to make one large photo. Online processors are used for this operation due to the high cost and complexity of the hardware and software.

The high quality single image is converted to a NDVI image. NDVI processing software is inexpensive and easy to use though the same online processors who stitched the photos offer this service inexpensively.

The agronomist uses both the normal and the NDVI images with more traditional methods to assess plant stress.

Plant stress can be detected well before it can be seen with the naked eye as well as after obvious damage is apparent.

The agronomist then performs "ground truthing" combined with other traditional methods to verify the NDVI data and determine the cause of the stress. Often the agronomist physically walks into the field and looks at the plants where the NDVI has identified problem areas.

The agronomist then makes recommendations to the farmer. If variable rate applicators are used by the farmer, then varying rates of fertilizer and pesticides are recommended which reduce treatment costs, protect the environment by reducing unnecessary over-applications, and increase yields.

The three photos below are all derived from only one camera. While you see a low resolution image here, the resolution of the actual photo is high enough to see individual blades of grass! The agronomist saves time because if bare earth, standing water or another obvious problem is identified using the image there is no need to walk the field. The sod farmer in this case uses this data to identify excessively large bare spots early on in the growing cycle to replant problem areas and improve yield per acre.
