I’ve had a few cases where taking off from the top of a hill for terrain capturing is very difficult. Case in point, this hill where all the vegetation is thorny bushes. If I take off from the lowest part possible, the top of the hill will have very little overlap whereas the lower parts will have good overlap. If i compensate flying higher I’ll get more overlap on the top, but I’ll start losing resolution.
I’ve read people asking for terrain follow and 3D flying, and although I would love that, the implementation seems non-trivial.
So, my suggestion for a step towards that direction is adding a toggle that recalculates the mission for a virtual take off point (which only has a different altitude than the home point)
