Could someone please explain if it's possible to record/save waypoints from a manual flight. I live in a pretty hilly place with lots of trees. Planning a mission using Tower is a joy over open land, but I'm having a hard time planning a mission over rougher terrain. I would like to be able to test fly an area manually, taking in to account the hight of trees, and the hilly terrain. I would like to be able to save a waypoint based on my current position in a manual flight. Is this possible at all? Any suggestions for dealing with terrain changes. I don't want to fly my drone into a hill!
