There are two ways to do that: 1)If the Input image is larger, the output also increases. If I remember correctly this happens. 2)You can stitch 4x 512p images together to get 1024p.
On any map finding the orientation of the drone is kinda hard on mid range, its good while its far way as it zooms, but for mid range i guess a zooming option is needed, im aware there is a zooming option ,but i coudnt spot the drone on mid range
