Drone data processing is one of the most demanding stages of the entire photogrammetric process. Each step - from image collection to map creation - requires precision and sophisticated software. Collected drone images must be uploaded to a specialized program, where they go through several steps, such as calibration, color correction and assembling them into a coherent map. This process can take anywhere from 1.5 hours to as long as 24 hours in the case of extensive agricultural or forest areas. It is worth mentioning that drones in precision agriculture must take extremely detailed images, and errors often occur at this stage. If they occur, the operator must correct the settings, which requires experience and knowledge of the specifications of the software used.

Advanced technologies in data analysis

Once the data is processed and a consistent map is obtained, analysis of the results begins, which is crucial for effective farm management. Depending on the client's needs, the data can be analyzed for a variety of parameters, such as assessing plant health, identifying environmental stresses, locating pest-affected areas, and planning future actions. With the help of indicator maps and numerical terrain models, it is possible to create 3D models of crop fields and determine optimal actions for improving crop health. In turn, 3D modeling helps to better understand field conditions, making it possible, for example, to spray or fertilize with precision. It can take 3 to 6 hours to create a detailed report for a 40-acre farm, and includes analysis that informs strategic agricultural decisions.

Key Skills: Why does experience matter?

Using drones for photogrammetric and remote sensing surveys is a task that requires considerable knowledge and experience. Drone operation and data management is not just a technical issue - you also need the ability to respond to problems that may arise during field work. There are situations in the drone industry where, despite good preparation of the equipment, there are unexpected difficulties. Examples include a problem with the drone's communication with the GPS navigation system, or unexpected weather conditions that can affect the quality of photos. These experiences help operators respond quickly and effectively, saving time and minimizing the risk of data loss. A well-prepared operator who has already dealt with a variety of situations is able to make the necessary corrections or quickly arrange for a re-flight.

The importance of legislation: Safety of drone operations

The use of drones in agriculture also involves compliance with strict regulations. Drone operators must be aware of applicable regulations and have the proper authorizations to conduct flights in public places or protected areas. Before each flight, the drone operator checks for aeronautical restrictions, such as the prohibition of flights in air traffic control zones. A collision between a drone and a manned aircraft, such as a helicopter, could have dire consequences, so compliance with regulations and safety in drone operations is a priority for professional drone companies.

Economy and ecology: The benefits of drones in precision agriculture

Costs in the context of drone use are not only related to finances, but also include saving time, reducing environmental impact, and lowering the human resources needed for work. The introduction of drones in agriculture is also an opportunity to minimize the use of fertilizers and crop protection products. Precise data allows fertilizers and sprays to be applied exactly where they are needed, resulting in reduced costs and less environmental impact. In addition, the multispectral analysis offered by modern drones allows early detection of plant stresses, such as water shortages, preventing possible crop losses.

Reducing emissions and minimizing environmental footprint

Drones in precision agriculture contribute to environmental protection in many ways. With the ability to accurately monitor the condition of crops, farmers can reduce the use of chemical fertilizers and pesticides, which reduces their runoff into groundwater and protects local biodiversity. In addition, unmanned aerial vehicles (BSPs) can perform inspections and surveys without the need for heavy equipment, reducing CO₂ emissions. In this way, drones fit in with the goals of sustainable agriculture and contribute to the Green Deal, which aims to reduce emissions and conserve natural resources by 2030.

Is it worth deploying drones yourself?

While there is much talk about the benefits of drones in precision agriculture, not every agricultural entrepreneur has the time and resources to manage the process themselves. Deploying drones on your own requires adequate investment, as well as advanced photogrammetric data analysis skills and familiarity with operating the equipment. A specialized photogrammetric survey company can offer a comprehensive service, from the drone raid to the analysis of the results and report preparation. By working with experts, the farmer can focus on managing his farm while the professionals take care of the technical side.
