Aerial Photogrammetry by UAV

We perform surveying and monitoring activities making use of remote-controlled aerial drones (UAV). With the latest generation of photogrammetric technique, determine metric data of an object (shape and position) is possible through the acquisition and analysis of a series of digital photo shoots. With this technique it is therefore possible to realize high-resolution three-dimensional models georeferenced in to the desired coordinate systems  thus obtaining:

• Digital color Orthophoto image at high resolution (3-30cm/pixel depending on flight altitude)


• Digital Terrain Models ( DEM ) excluding buildings and vegetation .


• Digital surface models (DSM) which also identifies buildings, infrastructure , vegetation, etc..


• 3D colored point cloud and direct export to cad


• 3D contours lines models at the desired equidistance (25 -50cm) .


• 3D vector models on triangular meshes ..


• Very accurate site plans and digital cartography


• Profile and cross sections.


•  Volume analysis

The use of drones can be useful and significantly reduces time and cost compared to other existing technologies for:

•  Transmission line Design (line route study,accurate digital orthophotos site plan, elevation profiles, etc...).


• Power Lines monitoring(existing towers, poles, insulators, and equipments...)


• Mining and quarries (Volume analysis)


• Urban residential districts and developmental areas


• Construction sites


• Disaster areas monitoring


• Pipelines design (line route study,accurate digital orthophotos site plan, elevation profiles, etc...).


• Road and railways design


• Crop and forest damages
