It may be early days for using drones – unmanned aerial systems (UAS) -- to map
construction sites, but technology and legislation are moving in that direction.
At the moment drones can fly within only a 500m radius of the ‘pilot’ standing on the ground, making the flight area a 1km diameter. This is the key limiting issue for any sector, especially road construction, says Jonathan Gill, a robotics engineer and a qualified drone
pilot for the past seven years.
The logic is that a drone remains withi
