I am converting over to Litchi from Maven following a hardware change (going back to Android). Maven only runs in IOS so I have taken the plunge with Litchi. I am using an Air2S as my drone.
I need a little help understanding the “Above Ground” function and whether I should be using it by default, or why I might not want to use it.
It seems to me (and that doesn’t mean much), that if this function is turned off then Litchi will base the drone’s altitude off the altitude at the first Waypoint, in effect treating the flight path as a flat uniform surface and calculating it’s (the drone’s) height off that measurement.
My understanding of the “Above Ground” option is that this is based off some map data (maybe Google Earth Topographical) data and vary the height you set to always be “x” feet above the ground based on the topographical data. This means that the mission will see the ground as an undulating surface and calculate altitude accordingly.
I am either somewhat close to understanding or completely off, thus the reason for my confusion and the question?
Anyone?
