Drones help expand the world's busiest airport

Drones and airports usually go together like oil and water, but you can't say that about Atlanta's air hub. The city has formed a partnership with 3DR, Autodesk and engineering firm Atkins that has drones mapping Hartsfield-Jackson International Airport as part of a planned expansion. The key to making it work was Site Scan, 3DR's autonomous data capturing tech. The drones could capture 2D mosaics and 3D point scans while staying well away from the airliners -- no mean feat when they're flying between runways at the busiest airport in the world (over 100 million passengers per year).
