Can drones be used for surveying: some tips about drone surveying

When undertaking drone land surveying, several key steps must be meticulously followed

Preliminary operations

The process begins with the clear definition of the survey area and careful flight planning, considering factors like flight altitude and image overlap. Once flight permissions are secured, the drone’s calibration is essential, ensuring sensors are accurate and photogrammetric equipment is functional.

Flight and Data acquisition

The drone executes its flight along a predetermined path, capturing sequential images or Lidar scans to gather data. After landing, this data is downloaded and processed with specialized photogrammetry or Lidar software, resulting in digital terrain models, orthophoto maps, and other relevant topographical outputs.

The accuracy of the topographic survey

The precision of a drone survey hinges on the correct execution of each step, from initial preparation to the final data processing. This meticulous approach is crucial to guarantee high-quality, reliable survey results.

What are the applications of drones in land surveying

The adoption of drone land surveying has unveiled a plethora of applications, revolutionizing traditional survey methods:

Topographic Surveying

Drones excel in gathering comprehensive geospatial data, which is instrumental in developing detailed environmental and territorial databases, leading to a profound understanding of land dynamics and resource management.

What is the difference between LiDAR and photogrammetry drone for land surveying



Which stands for Light Detection and Ranging, involves emitting laser pulses to measure the distance between the drone and the ground, resulting in a dense and accurate point cloud that is highly effective for precision mapping of surface features, even through vegetation or in low-light conditions.



This technique, on the other hand, uses overlapping images from a high-resolution drone camera to create detailed maps and 3D models of the surveyed area. This method excels in providing rich visual detail, allowing for the representation of textures and colors of the terrain, which can be particularly useful for cultural heritage documentation or environmental studies where visual context is key.

Benefits of drone surveying Vs. traditional land surveying

Weather condition

Factors such as humidity, rain, fog or smoke can interfere with thermal readings. Humidity, for example, can reflect or absorb infrared radiation, affecting the perception of heat.


Sustainability in drone land surveying is a key advantage. The use of drones minimizes the environmental footprint of survey operations by reducing the number of trips to the field and lessening the disturbance to natural habitats. This translates to not just ecological benefits but also economic ones, cutting down on the logistics and management costs typically associated with survey projects.


Safety is another critical benefit. Drone land surveying negates the need to expose personnel to hazardous conditions such as unstable terrains or areas with potential geological risks. This substantially lowers the risk of accidents and allows operations in environments that would otherwise be inaccessible or pose significant risk to human surveyors.
