Mission preview altitude not corresponding to flight plan altitude
I'm flying a DJI Air 2S with iPad mini (Version 3.3.2 (198) | Kernel 3.3.1 | iPadOS 15.4.1). On a sloping terrain I use Ground Level reference but during the Mission Preview, the altitude does not correspond to the altitudes recorded in the flight plan. Can you help please.

The altitude in the preview is the altitude above or below take off altitude
Correct, which is after the terrain follow has been applied.
Thank you, but I am not quite sure what to understand - must I accept the difference in altitude or is there something I can do to rectify it?
Ok I'll try and explain, say you are flying from a beach at 60 feet AGL (Above ground level) behind you is a 40 foot cliff, you fly to the inland side of the cliff with a height still set of 60 feet AGL, the drone will rise to that 60 feet AGL, but if you look at it in the preview it will show the drone at 100 Feet ATL (Above take off level), the 40 feet of the cliff height and the 60 feet you've told the drone to fly above ground level
Thank you Martin, that clears up my misconception. Obviously then I cannot use the Preview altitudes to confirm the altitudes recorded in my waypoint plan as I wanted to.
Just so I understand too, in Martins example, would the drone would automatically rise when it gets to the cliff's, or must there there be a Marker placed to tell it to do so? Like at the top edge of the 60' cliff. I thought in AGL it does not automatically/ continuously follow the terrain. (Which is different than Terrain Follow - and if I am correct, without one the drone will fly directly into the side of the cliff.)
George in my example it it would cross the top of the cliff 20 feet above ground level and yes it would be advisable to put a marker in just after crossing the top of the cliff to ensure it went up to 60 foot above ground level
To follow up on this principle - in my case I am flying on a sloping terrain from a high to a low altitude. By placing markers along the path I will assure that the drone follow the slope of the terrain?
That is correct, and you should see that slope in the 3d view.
