PHOTOGRAMMETRIC SURVEYS BY DRONE

The use of drones for photogrammetry, orthophotography and topography is becoming more democratic and offers innovative possibilities of use.

Application Areas 

The contribution of a drone is a real advantage for a surveyor or a topographer. Ease of use, automation and easy connection with data processing software (Pix4D for example) allow photogrammetry drones  to offer quite incredible performance.

Dr Stone offers a wide range of drones with high definition sensors particularly dedicated to photogrammetry and orthophotography. The drones we offer have centimeter precision thanks to multiple electronic sensors: altimeters, barometric sensors, GPS, GPS RTK or even a Lidar. This precision makes it possible to geotagger your aerial shots with a very high precision (of the order of a centimeter).

Dr Stone is a distributor in Africa of GEODETICS and GVL for LIDAR systems embedded in a drone.   We are also a reseller of Pix4D and Metashape solutions, post-processing software, especially dedicated to photogrammetry drones. They will allow you to perform 3D modeling,  of cartography or data exploitation.
