When executing a crosshatch square survey, the vehicle goes all the way up, then left all the way to the survey's corner before turning back to go down on the correct path.
As described by Tony White after a photogrammetry mission:
"Found a bug while field testing with a mission generated with new photogrammetry cross-hatch feature. Setup survey for north/south transects (~) and then checked box, it generated east/west lines. Would be cool to have ability to make this a different spacing than the original direction.
Uploaded mission, boat sets off, but when it gets to the north end of the survey area, it turns west, and goes to the NW corner of the survey. It then makes a 180 degree turn and returns back to the next N/S line... after coming back from the south edge, it again kicks over to this corner! I didn't bother stopping or debugging because the towfish seemed ok and wasn't being struck by BB after 180 degree turn, but this is definitely not a good thing for photogrammetry..."
