What elevation is the flight relative to in map planning?
Relative to the home point when starting the mission on the ground? Relative to the point in the air when the mission is started in the air? Relative to one of the points in the map plan?
I need to know because when I am mapping a large area, sometimes I need to drive to a new location after flying a segment. But the problem then is to make sure that the drone is flying the same altitude (above sea level) as my previous flight. My pan is separately get the altitude (above sea-level) for any place I launch from, and then adjust the map elevation for each segment of the larger area that I fly.
Of course, as usual, I am usually missing something obvious
