We would run a series of cross sections randomly around the project and have to achieve a passable level of accuracy.
I had looked into Drone surveying. The software to process the data was cost prohibitive. Instead I chose to invest in 2 roving GPS units which were still cheaper.
The GPS has been an eye opener concerning accuracy. When Inhave time I will post about that.

Drone companies are often our best clients. They can usually pop out a product easily for one building, or even a few dozen acres. Then some big client calls them for a 4 square mile area and they realize there is no way they can handle it. That is a piece of cake for us. We have done some much larger areas than that.
We can usually provide a surveyor the image at way less cost than they can do it on the ground. Even more so in rugged areas. We did one job on a oh my gosh, hurry hurry basis that was the bend in a river right after a mega rain fall and flooding. They needed to see the area, and it was still swampy mud, full of mosquitoes, ticks, chiggers and poison ivy. The surveyor said he was dreading and one employee threatened to quit before he went in there. We did it in short order and the final client thought he was hero to do it so fast. Of course it took 3 months to get paid. They all want the product NOW, but the payment is always slow.
We have a bunch of crazy expensive software. The Cessna 182 was not cheap. We can still do a 1/4 section or square mile section of land in short order, and for less than the surveyor would spend on the many road trips to the remote area to do the survey on the ground. Even more so if the area is really rugged with ravines and area no 4 wheeler can cross.
