okay this has been bugging me for like three weeks. doing a mapping job with my mavic 3 enterprise on dronedeploy, 75/75 overlap, flying at 120m, everything looks fine in the app and the individual photos look sharp when i check them. but when the orthomosaic processes theres always this one section on what ends up being the northern edge of the survey area that comes out noticeably blurrier than the rest. its not motion blur exactly, more like the stitching just went wrong there or something.

ive reflown that area twice and it keeps happening in roughly the same spot. the terrain isnt doing anything weird there, its pretty flat farmland. i checked for GCP coverage and i have points distributed pretty evenly. only thing i can think of is theres a tree line just outside the survey boundary on that side but im not mapping over it so i dont know why it would matter.

anyone seen something like this before? im kind of at a loss

tree lines can absolutely cause this even if youre not flying over them, the photogrammetry engine can get confused trying to match features near the edge of the mosaic when theres tall vertical stuff just outside the boundary. try extending your flight plan maybe 50-60 meters past where you actually need coverage on that side and see if it clears up. kind of annoying workaround but it usually fixes edge artifacts like what youre describing

could also be sun angle if youre always flying that area at the same time of day. if the northern edge is getting hit with low angle light at the end of your flight pattern it can create enough shadowing inconsistency to mess with the feature matching. what time are you usually flying? i had a similar issue on a site and just shifting my start time by like 45 minutes fixed it, which felt stupid but whatever it worked
