ok so this is frustrating. flew a pretty big site yesterday, maybe 80 acres, flat industrial area. mission looked fine in the app, did the whole thing autonomously, landed with like 30% battery left so it wasnt a coverage issue i think. uploaded all the images ? 847 of them ? and the processed map came back with these weird gaps, like two or three patches where theres just nothing, the orthomosaic has holes and the elevation model looks like someone took a bite out of it.

the images themselves look fine when i scroll through them, i can see the ground in all of them. so im not sure if its a processing thing or if my overlap settings were off or what. i had it set to 75 front 65 side which should be enough right. this is for a client and i really dont want to go back and reflfly if i dont have to.

75/65 should be more than enough so i doubt thats the problem. my first guess would be that the images in those gap areas have some kind of issue that the photogrammetry engine cant match ? could be motion blur, could be exposure problems if the lighting changed midway through, or even if the ground texture in those spots is really uniform (like a big concrete pad or something) the feature matching just falls apart. DroneDeploy isnt great at telling you WHY it failed, it just kind of silently skips areas.

check the images from those specific zones, look at the EXIF data, see if shutter speed dropped or ISO spiked. also what time of day were you flying, if you had harsh shadows crossing the site that can mess with matching too.

had almost the exact same thing happen to me on a gravel lot, turned out the problem was my SD card had a couple corrupted files and even though the images looked ok in preview they werent being read properly during upload. DD just quietly dropped them. check if your image count in the processing report matches what you actually uploaded, theres sometimes a discrepancy and thats where youll find the holes on the map.
