Good advice. Thanks!

These are all great answers, especially for a newk like me. Thanks so much. But just to clarify, supposed I'm on top of a 500 foot building, and assuming no blockage of GPS by other buildings, I can fly my drone, descend to ground level and fly it back up to the launch spot with no problems...

I was concerned that if the drone was measuring its vertical height from ground zero by, say, visual sensors, then if it flew out over a canyon at, say, ten feet vertical from launch point, and suddenly was over a canyon where the bottom was hundreds of feet lower, the drone would think it was...

Very good. That's what I wanted to know. Apparently the drone is not measuring its height relative to its launch point by sensors but by barometric pressure or GPS. Thanks.

Can I send my Mavic 2 down into a canyon and expect to get it back? Does it measure vertical limit from the takeoff point and can it subtract descent from that? Or does it measure from the ground under it? Am I going to get, say, 500 feet down into a canyon and not be able to get out again...
