In another discussion I presented the idea of a relay drone, a second drone which rises above obstacles to have a direct signal to the main drone. Here's a short list of who would benifit from this,
Police
Search and rescue
Surveyers
Developers real-estate personnel
Land owners who want to see what's going on, on their property
Anyone who wants to see what's beyond that obstruction, be it terrain or trees or buildings in the way.
This would allow a direct "line of site" from the relay drone which simply rises to a required height, to the main drone which may be flying beyond line of site and have signal loss.
