• The data capture systems consist of DJI aerial platforms (Matrice 200; 210 and 300) and cameras.
  • 3edata uses various camera models (Sony, DJI) for the provision of this type of service. Flights are planned with overlaps between passes of at least 80% transversal and 70% longitudinal.
  • Photogrammetric techniques make it possible to create 3D models of real objects from photographs of that object taken from different points. Like LiDAR-based systems, photogrammetry achieves good accuracies and is recommended for cartographic and topographic applications. Capture operations can be carried out with GPS systems with real-time correction, but it is also possible to establish control points for correct georeferencing.
  • The final products offered are the orthomosaic and the digital surface model.
