For farms seeking every efficiency advantage possible, the benefits strongly support bringing drones on board.
Types of Drones Meeting Agricultural Demands
Specialized drones built for agricultural use offer the payload capacities, range, and durability to endure farm work. The most common classes of ag drones include:
- Multi-rotor – These quadcopter, hexacopter, and octocopter drones use multiple propellers for vertical takeoff, stability, and maneuverability. They excelle at short-range crop monitoring. Popular models like the DJI Phantom 4 RTK often serve as introductory ag drones.
- Fixed-wing – With an airplane-style wing design, these drones cover much larger areas thanks to higher speeds and range. But they require space for runway-style launches and landings. senseFly and other brands offer fixed-wing options optimized for farms.
- Hybrid VTOL – Combining the versatility of multi-rotors with the range of fixed-wings, hybrid vertical takeoff and landing (VTOL) drones transition between flight modes. This allows launching and landing anywhere while flying farther. Examples include the WingtraOne and Parrot Disco-Pro Ag.
- Helicopters – More complex but capable of stable prolonged flight and heavy payloads, single-rotor helicopters like the DJI Matrice 200 excel at aerial spraying and mapping challenging terrain.
In recent years, companies have tailored drone models and sensors specifically to agricultural applications to better serve the market’s needs.
Choosing the Right Drone – Factors to Consider
With so many drone options now available, farmers must evaluate their specific requirements when selecting models. Key buying considerations include:
- Flight time – Longer flight times increase area covered per battery swap. Fixed-wing drones offer the most endurance.
- Range – How far the drone can travel from the pilot influences the acreage monitored at once.
- Payload capacity – Heavier sensor payloads like LiDAR require drones able to lift ample weights.
- Safety features – Failsafe GPS navigation and collision detection helps avoid mishaps.
- Camera/sensor capabilities – Visual spectrum, thermal, hyperspectral cameras each enable different analytics.
- Software integration – Look for platforms compatible with leading ag data software like CropCopters and DroneDeploy.
- Durability – Rugged, waterproof designs withstand the farm’s harsh conditions.
Considering these factors will help match the right UAV to each operation’s budget and needs.
Key Sensor Payloads for Specific Insights
The drone itself serves primarily as an aerial delivery mechanism for its sensor payload. Selecting the right sensors tailored to the farm’s goals proves critical. Primary sensor types include:
- RGB cameras – Affordable and ubiquitous, these gather visual spectrum images and standard videos usable for basic surveillance and documentation.
- Multispectral sensors – Using specific wavelength bands like near-infrared, these highlight crop health metrics like leaf chemistry.
- Hyperspectral sensors – Collecting a continuous spectrum, this data richly maps crop composition, moisture stress, yield clues, and more.
- Thermal sensors – By detecting energy radiated in the infrared spectrum, thermal cameras identify heat variances indicating irrigation needs and soil composition.
- LiDAR sensors – Using pulsed laser beams, LiDAR surveys create detailed 3D terrain maps showing elevation contours ideal for drainage planning.
The latest cameras integrating multiple sensor data provide the most insights from a single drone flight. But single-sensor payloads still deliver ample advantages over manual monitoring alone.
Drone Data Integration Drives Value
The data drones gather proves most valuable when integrated with analytics platforms turning aerial insights into actionable recommendations. Proprietary software like Crop Copters connects to drone sensors to map crop health spatial variability. While third-party platforms like DroneDeploy allow consolidating data from fleets of different drones into centralized databases for analysis.
By combining collected imagery with artificial intelligence processing, the integrated solutions can automatically flag potential problem areas and suggest corrective actions to the farmer. This enables putting drone data to work efficiently. However, data management and analysis represents a significant learning curve farmers must surmount to maximize benefits.
Here are some more details on key software platforms farmers use to analyze agricultural drone data:
