EU uses drone for infrastructure projects inspections

With the continuous maturity of drone technology, many industries can't do without the help of drones. Drones can reach the air that humans can't channel to help people complete many tasks, such as aerial photography, inspection, surveillance, spraying, mapping, etc. 

As usual, this kind of work is carried out by helicopters, which are very expensive and dangerous. Today, unmanned drones replace these tasks. They can perform tasks better, faster, safer, and cheaper.
