Aside from hobbyists, drones have major commercial applications. An area of specific interest is how this technology can help those in the engineering field. Often, engineers are challenged with inspecting tall or structurally deficient buildings. Google Earth doesn’t provide the detail that drones with cameras can show, and some situations are not safe or even possible for humans to perform a physical investigation (think high-rise buildings, towers, or roofs with incredibly steep slopes). Telescopic man lifts and scaffolding setups can be very costly and even require the building owner to shut down their business during the setup. Inspections from hanging scaffold rigs limit what can be seen. This is where drone technology comes into play
