Is there a way to load points and/or polygons into a flight control app and see those layers in a live heads up display? We have plots that are far apart on the landscape and it would be helpful to see where they are live in real-time.
There is no way to do that. The only thing that can be loaded onto the map is a waypoint mission which would include waypoints and optionally POIs.
You might want to get creative in using those two options to identify your plots.
