Altitude error in Dronelink Preview

Path 5    -3.9m Altitude !! is not correct

The  Flight Path view shows a Path at +-60m !

All the Altitude references are set to “Ground level”

Kmz  Google Earth preview seem ok, at the end you see at the details of an hotel roof.

Please comment

In January 2023 I will be in South Africa I hope there will be no errors  in my  flight plans!

Thanks a lot .  .  .  .  i am not a specialist in AGL  .  .  .  .

    The altitude reported in the mission preview is above takeoff location. It appears that you are taking off on a hill and flying below that altitude.

    Thank you for the reply

    If I play the Mission Preview in Google Earth it seems really perfect do you see a problem?

    If there is no problem this preview make no sense at all.

    What will happen if I execute this mission in South Africa?

    Will it crash?

    Thank for the reply

    It is allowed. It just shows you what the altitude will be reading when you actually fly it (a negative number because it will be flying below where you took off).

    I have learnt again .  .  .  . thank you

    I thought if you flew at -3.9m the Drone will fly into the ground so a crash.

    I therefore thought to update all the negative altitudes so they  all become positive

    Is there a course available that  explains the Dronelink  and Google Earth preview

    I still have to learn but without a course this won't work.

    Is it possible to avoid a crash via preview?

    Thank you in advance

    Francis
