A screenshot from a drone flight planning interface titled “DJI Mavic 3E Flight Planning for Topographic Survey Mapping” shows a mapped area with a green grid overlay and waypoint markers on the left. On the right, advanced settings display sliders for side overlap ratio (80%), frontal overlap ratio (80%), and margin distance. A note emphasizes that 80% overlap provides good photogrammetry results and should not be set below 70% for 3D mapping. A YouTube play button is centered over the image.
