When I press the "Return To Home" button, my Mavic first flies to the "Hight" I set in Go 4, before it returns. My question is: Is the hight measured above the Home position, or is it measured above the ground it is presently flying over?

Above the Home position I believe, where it was first measured

Yes (as in post #2). HomePosition is set as reference "zero"height.

Thanks guys. As always, it pays to read the other posts first.

An easier way to think about this -- when RTH is initiated, the drone will ascend from the current altitude displayed at the bottom of DJI GO up to the set RTH altitude.
