Drones are all the latest rage. Getting a perspective from a drone camera above allows one to see things you often can't from the ground. An aerial map can help inventory a site, plan a bike park, quickly investigate points of interest or better visualize a project area. In addition, with drones we can collect GPS tracks of existing trails much faster than a person walking can, aiding in map design.
Just need a simple picture or video for any industry, including real estate drone photos - YES, we do that too using DJI UAVs!
