The commercial real estate industry has become increasingly dependent on drones, with the construction and infrastructure sectors accounting for more than $45B of drones’ total $127B market value, according to PricewaterhouseCoopers research.

This technology is frequently used to assist with tasks on construction sites and to survey large structures for maintenance issues, spanning the buildings while gathering photos and videos of the property to determine if any maintenance is required.

Andy Osantowske, the senior unmanned aerial systems analyst at Evans Inc., a Falls Church, Va.-based consulting solutions firm, said people tend to immediately think of pictures with drones, but the use of this technology far exceeds aerial shots. Drones also are used to collect data for intelligence, analytics and surveillance.
