Our results : orthophotography and digital terrain model
Because view from sky is the most forward way to have a global idea of your assets, we operate flying robots (or drones) :
Multirotors (more flexibility)
Fixed wings (longer range of action)
They are autonomous flying machines. We program mission with waypoints and altitudes, area of interests, and send them to work with a high resolution camera.
Aerial mapping mission planning
Locations of 326 pictures to cover 100 ha with 5cm resolution
The principle of operation is photogrammetry. By taking a full coverage of overlapped pictures from sky, a global and geographical rectified image is created : the orthomosaic, or orthophoto, with a very high resolution of up to 2 cm or even less, depending on your needs. Another interesting deliverable is created : the DEM (Digital Elevation Model) made of millions of XYZ points.
