Of course, when it comes to business and agricultural needs, many drone users need much more than an aerial image-and this is where drone mapping apps come in. With an eye-in-the-sky view, you can get a better idea of what needs to be done (and where) much more quickly than you ever would through an on-the-ground inspection. Whether you need to survey drainage needs on a farm or assess work at a construction site, few modern tools are more helpful than drones.
