We have UAVs (drones) to perform photogrammetric work, which allows us to have much lower costs than those made with conventional methods.

For the realization of photogrammetry, we use either conventional means (airplane and helicopter) for large areas, more than 25,000 HA, such as unmanned vehicles (UAV / Drones systems) to smaller areas. The UAV / Drones system makes it possible to capture photographs at set points, thus obtaining the desired area and flying at heights lower than manned vehicles, thus avoiding the need to license to fly. This methodology together with the GPS by obtaining support points facilitates obtaining mapping.

UAV systems allow obtaining by digital photogrammetric techniques, accuracies beyond the reach of classical photogrammetry. Scheduling flights by inertial and navigation devices, can achieve digital models and ortho photos up to 2-3 cm accuracy in X, Y as well as photogrammetry with accuracies of 5 cm Z flying at 120 meters high.

The UAV systems allow analyzing from 200 Ha/day in the case of mobile wing system (QUADRICOPETRO), to 1,500 Ha/day in the case of fixed wing systems (plane). The devices are equipped with integrated GPS and inertial systems that as well as perform and record the information continuously send your location to a ground station, allowing real-time position. The UAV systems still rely on various types of built-in cameras (SONY NEX7, EOS 7D) and visual devices, which are used according to each specific need. All this equipment is innovative technology and allow the execution and obtaining high quality results. To ensure the success of each project UAV have integrated security systems and ground support from the moment of its takeoff to the final landing.
