I know in Litchi you can follow terrain by setting height above GROUND in Waypoints but how does a Waypoint behave above water:
ie: Lakes, sea, and Crystal clear swimming pools?
Hello there John. Good day and thank you for reaching out. Since this is a 3rd party application ( Litchi ), I hope that you will get the best recommendation from our fellow DJI co pilots who had used the said application. Just a reminder that DJI does not recommend you to your 3rd party application when flying your DJI Drones. These 3rd party applications might affect the said DJI drone when in use. There is a possibility that these 3rd party applications will be able work. However, since it's not optimized and tested by DJI we cannot guaranteed the stability of the said 3rd party applications if it will work all the time with no issues and might void the warranty of the said DJI product. Thank you and have a safe flight always.
