High point density and centimetre-level accuracy for advanced 3D modelling.
At DRONE & GIS, we deliver high-precision aerial surveying solutions through advanced workflows that integrate LiDAR technology, data intelligence, and specialised technical standards. Our approach with active laser sensors focuses on capturing topography with centimetre-level accuracy and exceptional canopy penetration capability, ensuring that scale and geometric accuracy perfectly meet the most demanding requirements of engineering, large-scale infrastructure projects, and mining.
To facilitate complex projects with maximum structural and topographic fidelity, we operate a robust technological ecosystem that combines:
High-Density LiDAR Sensors: Utilisation of state-of-the-art laser profilers with multiple return technology. These sensors emit hundreds of thousands of pulses per second, enabling vegetation penetration to capture the bare earth and generate structural 3D Point Clouds with an exceptionally high level of detail.
Inertial and Geodetic Positioning Technology: Integrated operation with high-performance Inertial Navigation Systems (IMU) and dual-frequency GNSS receivers (RTK/PPK). Supported by ground-based geodetic stations, we ensure fine adjustment of flight trajectories, delivering absolute georeferencing with centimetre-level accuracy and total cartographic reliability
Intelligence in Spatial Data Processing: Advanced processing on specific platforms for rigorous calibration and automated classification of the LiDAR point cloud. This workflow transforms dense data into exact Digital Terrain Models (DTM), essential for decision-making where traditional photogrammetry falls short, enabling the development of precise Digital Twins.
This solution is based on laser detection and scanning, utilising pulses in the near-infrared spectrum, imperceptible to the human eye. This method enables the exact measurement of distances and the detailed surveying of the surrounding environment. As an active sensor, the pulses hit the target and part of the light is reflected back to the equipment; the system estimates the return time of the pulse to determine the precise distance of the object, generating highly reliable three-dimensional data.
As a laser scanning method, the technology offers an extremely high degree of detail, capturing millions of points per second..
Thanks to the active sensor and excellent return rates, it is possible to penetrate dense vegetation and obtain terrain and structural models that are substantially more accurate compared to traditional topographic methods..
The use of Drone-borne LiDAR sensors eliminates the need for physical incursions that can disturb local flora and fauna..
By digitising the terrain from the air, we ensure the integrity of fragile habitats, providing exact data for ecological studies and environmental diagnostics without altering the natural state of the ecosystem..
The application of LiDAR technology generates high-precision topographic data, fundamental for supporting critical cut, fill, and grading decisions..
By ensuring the fidelity of the natural terrain in relation to the engineering design, a solid foundation is established for the infrastructure, mitigating risks of geometric errors and optimising the physical and financial programmes of the works..
