Drone use for Photogrammetry and Topography

Drone Photogrammetry and Surveying uses technology to capture aerial images and create 3D models, measure distances and areas, and monitor changes in specific areas. This technology is applied in construction, agriculture, mining and public safety.

The benefits of this technology include its speed and efficiency compared to traditional methods, access to areas inaccessible by foot and increased security.

Within Photogrammetry, high-definition images captured with drones allow three-dimensional reconstruction of objects and scenes, applicable in various situations such as infrastructure, buildings, escarpments, bridges, archaeological excavations and more. This improves project planning, design and management.

In addition, drones generate highly accurate digital terrain models such as DSM and DTM, useful in hydraulic assessments, design of lamination and evaluation of locations for construction.

The creation of 3D models using remote sensing and photogrammetry technologies is ideal for capturing point data in situations that cannot be recreated, such as archaeological excavations or accident scenes, geological analysis, and seismic and structural assessments.

Orthophotos, geometrically corrected aerial images, are essential in cartography, urban planning, land management, environmental analysis and engineering studies.

In topographic surveying, drones are essential for detecting and reconstructing large areas such as quarries, cliffs and riverbanks. Accurate georeferencing is crucial, and the point cloud obtained is used for subsequent topographic elaborations.

Drones are also used for surveying infrastructure or buildings, using advanced techniques such as photogrammetry and laser scanners to obtain detailed 3D models and thermographic control. The integration of laser scanners and GPS supports the process, providing detailed information on materials and deterioration in historic or protected buildings.
