If you're attempting to convey the view surrounding a marsh, river, creek, ocean, or lake, there is simply not better way to define the space or area than through the use of a drone.  Users quickly identify which area of land is being referred to and obtaining the approximate  dimensions of the surroundings.

​

This also applies for large acreages or lots.  The drone is able to not only see the entire lot, but also the surroundings.  If you need hyperaccurate visuals for a particular lot as well, just as for an orthographic map.  Detailed photos will be reproduced down to 0.3in / pixel.  For reference Google Earth / Maps is 15 Meters / Pixel!
