Just from a mockup that is almost 12 hours of flight and while DroneDeploy can process it I don’t think you will be able to export it unless you do a lower resolution. I would suggest quading it or breaking it up into manageable sites from location where you can maintain VLOS. If you have a KML of the master site I would love to take a look. PM me if you prefer.
The way to export is to process groups of flight and bring them into QGIS. From there you can overlay them and export the master. I hope you’ve got a strong computer.
Thank you for your reply. I would most definitely map this in sections, most likely about 150 acres at a time and then move to next location.
The largest mapping I have done was UC Merced 160 acres, I split that in to two sections moving from one to the next for the very purpose of VLOS.
