I ought to look into this.
I’ve seen lots of real estate ads use them now - video.
I was on a “webinar” where they had several drones going through a large building under construction and using LIDAR(?) - or something similar. It would scan the construction area and compare the “as-built” with the blueprint at the end of each work day. That way if something was out of place (like an I-beam) they could remedy it right away.
I looked on youtube for the construction stuff. Some amazing stuff. Also lots of videos with “You Too Can make MILLIONS in the Drone Business”. To find out how - buy my book and drone for under $1,000 and get started - NOW!!
