The use of drones for roof inspections is safe, fast and it saves money. The use of 360-degree virtual tours drive sales and visits, whether that is of homes, cars, pubs or restaurants.
Drones completely eliminate the risk of falls from height. They enable main contractors to keep tabs on the progress of construction projects, without the need for "boots on the ground". External drone imagery can be coupled with internal 360-degree virtual tours for the purposes of progress monitoring. The virtual tours can also be incorporated with BIM to compare as designed with as built.
Virtual tours of homes, cars and restaurants are far more immersive than flat photographs and videos. They allow the viewer to take control of what they are seeing, rather than simply watching from beginning to end. The viewer takes control. And the viewer is much more likely to do what you want them to do and come to see what you have to offer and make that purchase.
