Traditional and established methods of surveying often involve considerable human resources with all the health and safety issues and costs that are inevitable.
Aerial surveying can be undertaken in a broad variety of scenarios and applications, from small buildings to skyscrapers, fields to industrial estates, powerlines to wind turbines. We have to work in all manner of environments, many of which are hard to reach and some, dangerous to access.
Each environment and situation bring with it a new challenge. We are used to replace human operatives and specialist equipment when extreme heights are involved, and drones are perfect for surveying hazardous environments. It could be that the size of area to be surveyed is so large that only an aerial survey would be cost effective. There are huge benefits associated with aerial surveying which industries of all types are starting to appreciate.
