Field measurements by drone: Modern methods and their application

Drones have revolutionized the surveying industry, offering faster, safer and more precise methods of collecting field data. With the ability to fly over hard-to-reach areas and capture detailed aerial images, they are becoming an invaluable tool for surveyors, engineers and construction companies.

1. Speed and precision: Drones can collect data from large areas in a matter of hours, providing information with accuracy to within a few centimeters. Ideal for creating maps, orthophotos and 3D models.
2. Lower operating costs: Fewer people in the field, shorter lead times and no need for expensive ground equipment translate into real savings.
3. Access to hard-to-reach places: Mountains, forests, hillsides, high altitude infrastructure? For drones, it’s not a problem. They eliminate the need for human labor in risky conditions.

Drone images are processed into precise 3D models and terrain maps. Used in urban planning, environmental protection, infrastructure investments.

Bridges, roads, power lines or roofs can be quickly and safely assessed for damage, without the need to erect scaffolding or take facilities out of service.

Changes in land cover, erosion, water quality or air pollution can all be regularly monitored from the air.

Problems: limited flight time, vulnerability to weather conditions, regulations and the need for a license.

Trends: better batteries, autonomous flight, integration with AI and IoT, enhanced sensors (LiDAR, multispectral, thermal imaging).

Drones are the future of field surveying. They offer speed, precision and safety, and their capabilities continue to grow. The surveying industry is already taking advantage of their potential, and there will only be more of them as the technology develops.
