A comon thing here were i work and fly is that our customers who wants to fly and inspect forest (government people who inspect that the land owners have cut the forest in the correct way) might send me a bunch of objects (gps positions) they want to go to. It's usually a cluster of positions that could have a couple of hundred of meters between them and sometimes kilometers between them. Today we have a system for optimization, but it's old, verry slow and complicated.
