My key worked, how is it with yours, now?
Ehm, I am trying to build up some trust in ground enabled waypoint missions. 
But right now I am a bit concerned about that the altitude is not corresponding with the sat-pictures on google.
Which at least should keep people away from planing to little flight heights over ground. (Me?)
I did set up a plan in litchi.
Actually, I used google earth for the path , following this video, and imported the .kml into litchi, after.

Not sure that has advantages, but I did look into this before.
After I saved it as kml, imported that to Litchi, created the mission settings (POI, ....).
Exported that as CSV, did the conversion with CSV2JSON and got a savedPlan.json PLUS a savedPlanagl.csv
(where did that come from?)
Imported the json into FF6, and looked at the agl.csv in Litchi
I have not flown that mission, yet.
And I will (have to) do different settings, before I do, b/c the height of 20m should have shown the above ground effect, but could get me on some wp's (7 to 8) in trouble.
Because on the reservoir (like on beaches), there is very good to see, that the elevation from google is not on the spot!
I think, the drone will fly more or less the path, that is to see, in the pictures.
Which sees the highest ground on the water. But even if the reservoir would be full, it would be some meters under the top of the dam.
Also I would assume that I end up in the trees, despite that the ground near the road is as high/low, as the tree ground is.
But: the elevation numbers on google still got lower behind the road.
That said, with 40 or 50 m flight height it will work out, I think.
But I will "loose" wp7 and 8/9, for flying it with the set up of 20m
And I really wanna see, if this way the Anafi could fly a mission lower than starting point ;-)
But since there a light poles on the dam, I try not to push it to much in the beginning.
Here the pictures to the project:

I hope that I can fly this soon. Will today change the mission a bit, deleting 7 and 8, perhaps 9, and then wait for the right time.
