Does anyone know if you are able to fly a double grid mission in DJI pilot? I can’t seem to find this option anywhere.
There isn’t. You will have to create a mapping mission and then copy it and rotate the pattern, so you will end up with two missions that you need to execute.
In DJI Pilot “Mission Flight” when you have chosen “Create a Route”;
You have to choose “Oblique”, not “Mapping”. Then you will create 5 grid missions, not only 2.
So if you don’t want obliques then do what @sebastianstumpf recommended?
If you want to do nadir photos in a double grid, you will need to create one mission with the orientation i.e. N-S, then copy that mission and rotate the orientation of the grid by 90° (in this example E-W).
So you end up with two missions, that you have to execute one after the other.
